Hello there,
I've installed roundcube webmail 5 on the server also keep webmail 4 on the server.
Then, I got the issue about some user can not use new webmail, when they have logged into the webmail5 seems the webmail not functionality, they can't click or do anything on the webmail.
But when they've tried to login to webmail4, everything working fine.
Look weird? because it's not working with some user not all email accounts on the server.
Could someone has experience about this issue let me know how can I fix it? or the solution to debug this issue.
Thank you in advance.
