Hello and thank you for your reply,
We still have problems.
1) Conditions do not work in backend : backend profile updates can not be saved as fields that sould not be filled in are required to be filled in by the system.
2) When registering we still have this message/problem : "Session expired or cookies are not enabled in your browser. Please press "reload page" in your browser, and enable, and enable cookies in your browser. please refresh/reload before fillin-in".
3) Sometimes in backend I have a Javascript error : a jquery script blocks and break the browser.
Regards
