Okay, I know that unless my site gets hacked I really don't know how well this works. However, with that understanding, it installed well, that is, after I disabled my "register global" in my php.ini file. I use Hostgator and they require it turned off thru the php.ini file. They tell you in the forums that you should have register globals disabled because, really, without it - any security add on is really useless. I believe them so mine is disabled! Anyway, thanks for the plugin, I'm trusting it will help keep my client's site safe (especially since it is going to be hosted on Siteground's server - the guys who wrote the plugin)
As far as the footer, just take it out of the plugin file. I didnt mess with the php code, just the html section that puts it in there.

Can't really rate this except to say that it caused my site to go offline with errors. I guess I'm not allowed to post the error message here but I did see that's it's a common problem in their forum. Apparently it's incompatible with something on my site. Too bad, I would have like to use it. Linkbacks is not something that would prevent me from not using an extension, they are too easy to remove. Some of you really should take some online HTML, CSS, and PHP courses, many of them are free and you'd never have to complain about linkbacks...just remove them!

The thing that i find with these type of plug ins, is that you never really know if it is installed correctly, but i guess it did. the only thing is that i see people have commented about the backlink, but i'm not seeing any back links at all?? other than that, the installation and setup was really easy with only one section to set up to your specific requirements. i think it was great :)

It takes what the title says to install it. Just download the plugin, upload and enable it. Well, another 5 seconds (as already said) to remove the footer.

The worst thing fo this plugins are that you don't notice if they are beeing useful, as the block the own problems that make you need them! :P

Thanks for publishing the plugin guys!

just enable and that's it!!

as for removing the "joombla extension by siteground" water mark at the bottom of the front page..

as stated by CarlG (a few post below)...

but it's gest if you use remove the URL and the text

and leave the codes be!!! since if you remove the codes.. you site will not even load!!!

my advice to remove the watermark is

1- copy and paste your codes into a txt file before doing anything.. so if you messed up.. you can just re-paste them

2- if you want to remove the trademark of the front page..

remove THE URL and the TXT in the Replacement line

so what you looking for is and joombla extensiones by siteground..

or soemthing like those two within the $replacement =

that's all

Easy install. Just do what the other reviewer recommended to remove URL on front end pages. Took about 5 seconds.

Thanks so much for this FREE security extension!

This extension is released under the GNU public licence... therefore, that means you can modify it according to your needs... You can remove the publicity by removing these lines in /plugins/system/jhackguard.php

function onAfterRender() {

$output = JResponse::getBody();
if (!(preg_match("/sgfooter/", $output))) {
$pattern = '//';
$replacement = "Secured by Siteground Web Hosting";
$output = preg_replace($pattern, $replacement, $output, 1);
return true;

Was disappointed with this as once installed an 'Extensions by Siteground hosting' link appeared on every page and even in the backend!

When I uninstalled the plugin it was still there and they wanted to charge $49 to advise how to remove it!!

We have extensively tested the plugin and we can guarantee that the link does not stay after the plugin is uninstalled. I would guess that you have some cashing extension that causes this problem with your particular websites. However, we cannot say for sure without testing it on your website.

We would like to thank you, however, for the feedback about the backlink to our website. We have added this token of appreciation since it is a standard practice amongst such extensions but we will consider making it optional for the next versions.

This is a great, anti-hack (or anti hacker) security plugin.

However, I agree with everyone here who said that the back link is simply cheap, and makes the developers look more greedy than credible. Should be an option.

Note to the JED Team:

Please consider reviewing your criteria for a non-commercial plugin. The back link should optional for user, otherwise all our sites will look like link farms. The great gallery component Phoca, and many others are in the same boat.

I really don't know if this plug-in work or not? But I do know it creates a great deal of errors when it comes to the components and plug-ins that I have. When logging out of Jomsocial 1.8.7 it create an illegal key error, plus created another error when I was using Virtuemart 1.1.5 the new version. So until it has a little more wear and tear I am not going to use it. Because I can't have my members running into errors pages.

Another thing: placing the Siteground link on one page is fine, but when it places the siteground link on all my pages and throws my template out wack, I was left with one choice remove the link...

But what good is this plug-in when everything you have or want to use conflicts with it? Just do a search on this plug-in and it clear more than 50% of the people thats using it or have used it have un-installed it. And I still don't know if it ever worked! But I do know the link to Siteground website worked! And no one in this review section knows if it works or what it does? There no read out or any that shows what it blocked or prevented! Wait, here a thought and a scary one at that maybe the hackers was supposed to see the Protected By Siteground and run away...or find another website to hack into...

No one that have downloaded this plugin knows what this plugin does?

Why people put bad review? You can always cut away footer link and use it. Try to vote for tool not emotions.

[ First time to give a rating and I never thought that it would be a "Very Poor" one. ]

Like all the high quality security extensions I've tried and installed on all the sites that passed through my hand, I'd love to use this one.

But adding a "Secured by Siteground Web Hosting" footer on all the pages is a huge turn off.

First, and as was said before, it's misleading. Second, does it have to be on all the pages?

I really liked it when I looked at the code, it's just sad that I can't use it, more so recommend it.

I hope you'll add an option to disable the footer. If that's not possible, maybe you could provide a commercial version so that people who really want to use jHackGuard can do so but without the Siteground footer.

I used this component before it was added here, it is great, but since my site is not live yet, I asked my web host to use it because of their name appearing, they read the review and they highly recommended to use it. Great job, keep it up :)

I have reluctantly uninstalled this as it display this message on your pages'Secured by Siteground Web Hosting' This too much in your face for my web host who is not Siteground. Its a shame as security is a concern for all of us. A parameter to show or hide this would then make it optional but this is not available. Please do consider this.
