For example the ZIP code is not mandatory to all countries and needs to be setup for every single country manually. At least I cannot find option to make it mandatory to all countries.
Other thing is the order status which is not easy to setup to shipped. Too much scrolling.
When you see the orders listed, you cannot see which products are ordered as a list. You need to click the order and scroll again.
PayPal subscriptions is not supported unless you buy $45 additional mod for the opencart.
There is all kind of small things which make this component potentially a great one but it needs more development to my taste.
Upgrading from 1.2.1 to 1.3.1 messed up the layout of my site totally and I needed to go back to previous backup.
After I went to the previous version, the component asks a login details at the Joomla backend and I cannot do anything. I have no idea what this is about. I am logged in to Joomla backend but I cannot use the MijoShop anymore and it asks a username and password. Cannot find any details what I need to put there from documentation.
I don't say this component is a disaster but I am scared after using some of the Dioscouri extensions before that the developers goal is to make this component hard to use out from the box so the paid users need to use customer support a lot to make it work.
I think the customer support is fast and will help you to set the shop but lack of PayPal aubscriptions and too much scrolling to get the information I would like to see listed at the backend make this uncomfortable to use.
