Roundcube login redirects to blank page

Hello,
I have many CWP PRO licences where at EVERY CWP installation I am facing the following problem:

When trying to login to my-IP:2031/roundcube/ then after click on Login I get a blank page and redirect to my-IP:2031/roundcube/?_task=login again.

Please advise.

tail -n 50 /usr/local/cwpsrv/logs/error_log

The latest include:

(thanks)

Nothing there.  use the -n 50, and hit the roundcube loging just before grabbing the log.

I tried to loggin to Roundcube, but blank screen after that. Then I copied the log.

Roundcube does not even login.

what happens when you use port 2095?

Wondering if you're still willing to share your thoughts on port 2095.  I now have this situation with webmail/roundcube screen coming up blank.  Connecting to port 2095 also comes up blank.  As a test, I temporarily disabled the firewall and the page is still blank.  Thoughts?

Problem solved after anything is updated in CWP. Thanks!

Good to hear! rcshaff's advice is (as always), spot on. Try :2096 (HTTPS), :2095 (HTTP), disable the firewall or specifically whitelist your IP address, disable any ad blockers or privacy tracking plugins in your web browser, try Private Browsing mode, try another web browser, use a VPN -- all these are basic steps if you have connection issues with any of CWP's HTTP/HTTPS-accessible services.

Thanks.
