@pitaj great, thank you very much!
Currently I have solved some issue but still not this.
I cannot deactivate all plugin but I will ask to the company team to look into this issue.
If I will find a solution I will post here.
Really strange because I think the only new plugin activated was deactivated and users tab still not working also load directly a profile is not working. Editing mine profile works.
Strange, not found error for communityaddress.ext/user/nickname but work if the address is communityaddress.ext/user/nickname/edit
Anyway this message is to say thank you to you, great help and fast. Thanks!
