Multi Sites Popular Component

JMS Multisites extend joomla with Multi Sites and user sharing. This allows multiple domain names or sites to have their own joomla configuration file using the same joomla installation. Possibility to share the users, and extensions like VirtueMart, Community Builder, JomSocial, ...
With this new feature you can share the joomla files and folders to create totally independent web sites.
This simply the maintenance of Joomla as you have only one instance to update for all the websites.
With JMS you can create website based on website template to create new slave site.
A "maintenance" functionality is also provided to help supervising the extension installed in each website with their datamodel and help you fix the potential datamodel errors.
As each website has its own joomla configuration.
You can decide to use:
- One database for all the websites. In this case, you must specify different database table prefix for each websites.
- Two databases (One master database and One slave database). This architecture is advised when you want to install JMS on an existing website and you are limited in the number of databases you can create (or disk space).
- As many databases than there are websites. This is the most flexible architecture where each websites works with its own database. This is generally the architecture adopted by joomla when you create multiple websites.
The content of each website is totally independent. This means that the content (articles, news, forum, users, ...) are NOT shared.

The setup of each configuration site consists in using the standard joomla installation mechanism.
In the administration of a 'Slave' site, you can re-install/uninstall extension previously installed on the 'Master' site.
The 'Master' site is the one where you have installed the Joomla MultiSite component and where you manage the 'Slave' sites.
Additional controls are performed during the installation/uninstallation of an extension in a 'slave' site.
Before executing the standard joomla installation, it is verified that the extension you request to install has exactly the same name and same version number to avoid inconsistency between all sites.
This additional control is performed to ensure that you will overwrite the current installation with identical files that you originally installed.
On 'slave' site, uninstalling an extension consists in a joomla standard cleanup of the database. The files present on disk for this extension is not deleted to avoid disturb the other sites.

You can also replicate a website into the same database or in different DB to avoid re-installing the extension in each slave site.
On Unix platform, it is also possible to deploy a slave site into a specific folder.

You can also share user and share the content of a limited number of extensions.

It has been several years that I have been using this extension. Earlier, I purchased the 1.1 version. Then I had to pay full price of the 1.2 because there was no update version.

For some reason there are problems in the logic of programming. Since years I hoped that this developer will learn to understand the problems of admin and will remove the faulty logic. He does not.

Now sometimes the saving of new sites does not work and after saving it gives a white page. It in fact did save the configuration but somewhere in the middle it dies.

Hence I ended up many times to completely remove the component and reinstall it all again. After that it works.

Now I was trying to uninstall a couple of components from the master site to be removed from the slave sites (it has a management tools inside).
I saw multisite in the newly created site. So I uninstalled it. I found that the newly connected site was uninstalling the multisite component from the master site.

The newly created site did not create the configuration of the slave site and hence was getting to the master site.

I did not realise this immediately. So I deleted all the mysql tables from the slave site. Only then I found that it was connecting the master.

Those are the practical problems in using this component. It works indeed ok.

There is an installation directory of joomla. I thought that the developer will somehow change the name sometime in the login. Now the multisite uses this installation directory for some parts of the module diversion. So if your configuration gets damaged like mine, then it will point to the installation. I fooled myself when I began to reinstall every thing again and found that everything was in the database. Only the multisite was screwed up. After renaming or backing up it works agains.

So this is a nightmare it something small goes wrong and the whole installation does not work.

Now the programmer does not offer any forum. Emails does not always gets answered. So there are not much possibilities to complain.

It would be better to change the handling of all the sites for the administrator.

I write this because I was just now fooled by the component and was furious as this was just the programing logic that the guys does not change it since many years.

As the customer does not seems to have found the forum, it is possible either to access it from the "support" button present in this page or the menu forum present in our website or directly at the address http://www.jms2win.com/forum

This extension does exactly as advertised and does it well. There is some complexity to it, but remember that you're dealing with an operating system, a web server, Joomla! and a complex extension all at once. We've had a few installation issues, mainly due to unix permissions and apache configuration, but none unsurmountable. I can highly recommend this for people that need to run multiple sites on one server.

Edwin's customer service is second to none!

Great program, any "bugs" I came across were of my own missunderstanding of the way it works. If you have no tecnical understanding of MySQL - invest in an hour of Edwins time to go over your set up. Well worth the money! I paid for a couple of hours of time though and was VERY happy I did. Edwin is extremely knowledgable, And taught me what I needed to know to get this program working to save me hours if not weeks of developement time. Edwin was even able to help me integrate a different program into Multisite's sharing setups.

Wow - I have just found exactly what I needed with Joomla Multi-Site (JMS). I could not get past what was inevitably going to be a nightmare as I have grown in my site building to a point where even just the new version updating would have taken me days.

After finding JMS I was skeptical but went ahead hoping for the best. Wow was I surprised! Not only did JMS make it possible to produce hundreds of Joomla sites with just a single install, it did it in such a way that we were able to build 400 sites in a single day.

I originally wanted a multi-site solution for maintenance issues going forward but found not only a solution for that but also found a solution that drastically reduces the time I now spend building profitable sites not to mention the additional benefit of the space it saves on the servers.

If you are growing and have found the need to have multiple sites this is your solution. I wish I would have found it before I started my second site.

Support has also been top level.Edwin knows his stuff and is constantly adding new things to make this solution even better!

This component allowed me to use Joomla! for a large multi-site configuration rather that moving to a different CMS. Making updates to 10 sites at once through shared template files makes the update process much easier. Not to mention Joomla! version updates. I decided to write this review because of the customer service I have received from the developer. He provides top notch technical support through forums, emails and video.

JMS2Win has a lot of potential, but unfortunately, its quite buggy. For example, with core SEF on, many of the form functions do not work - like creating/deleting sites.

This is the most comprehensive component I have ever seen. The possible configurations are endless.
I am using Jms Multi Site for a client who wants to manage several sub-sites from a central admin panel.
They have one main website, and several sub-sites. Each of the sub-sites will contain a smaller subset of the main articles and products, with a few that are unique to that site.
With Jms Multi Site, and some of the excellent add-ons available, we are putting together a system where they will be able to manage all their VM products, articles (and soon even contacts) via the main admin panel for their master site.
The only thing that they will need to manage from separate sub-site admin panels is the unique menu for each site. Everything else will be handled from the main master admin panel.
Of course, this represents only one of the many ways that Jms can be configured for multi-site management. Many people are using it for their many Joomla! clients who have completely different websites. Sharing the core Joomla! engine allows for developers to host, support and upgrade many Joomla! websites easily.
I recommend this low-cost component to everyone! There are many add-ons for it, so you can choose what you need.
Purchasing this system for my client has saved them so much money. They probably would not have been able to afford the development costs of engineering a system for their needs. But Jms saved the day!

I purchased the multisite component, menu items and virtuemart plugin. I was able to make the installations needed and it saved me so much time and effort it cut down my project plan by a week. I had a little trouble re-downloading the component to install on a another site but Edwin responded within less than 24 hours with great support a new ID link. After that I was able to download all of the plugins and components.

For those of us who have tried having one site with multiple domains but one database, this tool is an answered prayer. I had done it manually before but to be honest its messy, it takes longer and it involves too many headaches. It is worth the money and I don't consider it a lot.

Thanks Edwin!

Thank you very much for this component. It's excellent. I am able to manage multi sites on the same database and folder. Plugins, components and modules sharing easy for each slave site.

Thank you..

Edwin is an amazing developer and has put out a very well designed product.

This solution, which replicates database tables, doesn't rely on synching, so data is always the same.

I used it to get Community Builder users across multiple domains and have loved it since, while articles, can be different.

Enable what gets duplicated by component, module or article. The possibilities are endless.

I am very impressed with this program. The support is great too, very fast! You have to be comfortable with how database structuring works, but the tutorials make it easy.

I've been using the old branch (1.0.xx) of Multisites for 2 Years now and it works great. I use it as my development site, so I don't have several Joomla installs to take care of on my development server.

The best about this extension is that when you need support, you get it almost instantly.

Thanks Edwin!

Superb support by Edwin and JMS Multisites works extremely well, however configured.
For those familiar DNS and a solid understanding of file structures and Unix systems, it is straight forward enough. The videos on the JMS site are pretty good and if I could offer a small criticism, it would be the English language translation in the manual. Other than that...very solid!

At first this seems complicated and it might take a few attempts to get a successful slave - the excellent tutorial videos helped me a great deal. Once you've got the hang of making one, you could easily make a hundred.

I've tried other solutions, but this one worked best for me with it's built in support for third party apps like virtuemart and community builder. It's a very powerful feature, well worth the cost and more.

I can't give enough praise for this component, bottom line is if you want to share a user database between a number of websites then this is the answer.

Edwin the developer is one of the most intelligent and experienced developers I have ever worked with. Not only is his product incredible, but his support exceeded my expectations as well.

When I hired him to help me configure a few things, he went above and beyond, and spent his entire Sunday afternoon helping me make a Monday deadline I had. He could probably do in an hour what would take an average developer 5 hours.

I not only recommend getting his product, but hiring him to configure it for you as well, you won't be disappointed.

My title says it all... It's now possible to control whatever extensions are installed on each website, create a "template" and easily launch a new website based on an existing one.
I can now share or not (it's up to me) users, configurations, database tables, update extensions...
You will need to get used to manage websites with JMS control panel, but it will be very worthwhile! It was money and time well spent - some days after install I can see the profit!!!

Whenever a doubt or any other support is needed, you can count on getting a solution fast - great work. On top of that, community is growing and you can learn from other users experience also. Check their website.

Definitely: Recommended for anyone managing several websites or planning to do so in the future.
