Hi,
@alexmartin :
it seems to me the Ajax is one of the problem
Yes, that's what I concluded in my previous message to you. Basically, the login seems to work when ajax is not used, but even then, the state of the login is not kept after a refresh.
@RAYFormation : you mentioned CB. Note that CB has (or at least had when I checked 10 years ago) some weird integration with Joomla's user system. Years ago, we made some extra code in HikaShop's registration system specifically for CB. Maybe it's linked to CB ? I don't know if @alexmartin is also using CB.
Since thousands of merchants use HikaShop 4.7.4 without login/registration problems, the issue must be linked to something really specific to both your websites.
What could be interesting would be to go through this:
forumpostassistant.github.io/docs/
and that you both post the information about your website here. By comparing both, we might be able to find what you both have and which might be different from everyone else.
Also, from what I could see here (
www.hikashop.com/forum/checkout/902786-p...within-checkout.html
), it could also be something related the how the web server is setup. If you have access to another hosting, it would be interesting to make a copy of your website on that other hosting and see if you have the issue there. Chances are that you won't have the problem there.
