Users cannot login in cwp

A lot of users cannot access in the control panel but in the admin panel they seems connected. Fresh installation on VPS Centos 7  cpw pro latest version. After login a message says: please wait, but after a couple of seconds the url add /login/ and return in login page. This is very strange because only one user can login withouth problem other users no. I try on differrent devices and different browser: safari, mozilla windows mac e ubuntu. 

 

Please check that the accounts that login have a package assigned, or that there is some language or theme defined

Great! You gave me a tip on where to look. Each account had an assigned package, language and theme, but only the account that was logging in I had changed the package after creation, so I tried to re-select the package for each account and voila ... it works! Now everyone can log in on user panel. It's certainly a bug. Thank you very much

I forgot that it you also need to delete each user's .conf folder, then update the package by reassigning it. Maybe it could be useful to someone
