Title: User cpanel URLs and login completely broken since CWP 1.18 update
Post by: simonjwoolf on October 07, 2026, 08:42:58 AM

Since the CWP update to 1.18 my user panels are completely broken. I see a message in the admin that I should stop and start the firewall. This did not make any difference.

The links from the admin panel all produce 404 errors, and if I try to manually login then I get a 500 error. I took a log in the apache logs but cannot find anywhere where the hostname access is logged.

I don't know if this is a reoccurrence of the problem described here: https://forum.centos-webpanel.com/centos-webpanel-bugs/fix-user-panel-login-is-not-working/, or something new?

CWP stores access and error logs of the panel in:

/usr/local/cwpsrv/logs/
/usr/local/cwp/php71/var/log

Many thanks. This reveals a whole stack of unexpected errors. I'm lost!

According to the error, PHP open_basedir blocks access to the files of the panel:

What kind of URL do you use to access the panel ? Is it something like:
https://cpanel.domain.com ?

If so, try:
https://domain.com:2031/

Did you change PHP settings recently ?

Can confirm user panel logs in fine on version 1.18

No I didn't change any PHP settings. And I can't access the panels via either URL format.

I did deal with a similar hacking exploit to the one you described, I wonder if I accidentally locked something down.

Did you try disabling mod_secutity?

1. Open the file:

/usr/local/cwpsrv/conf.d/users.conf

and check all lines that contains "open_basedir ...".

Make sure the open_basedir is configured at listed below:

Code: [Select]

fastcgi_param   PHP_ADMIN_VALUE "open_basedir = /tmp/:/usr/local/cwpsrv/var/services/users/login/:/usr/local/cwpsrv/var/services/users/cwp_theme/:/usr/local/cwpsrv/var/services/twig/";

You should see 4 absolutely identical lines there.

Make backup and fix the lines if they have different values.


2. Open the file:
/usr/local/cwpsrv/conf.d/users/USERNAME.conf
(USERNAME is the username of some regular (not root) problematic account)

Check the line with open_basedir there. It should be:

Code: [Select]

fastcgi_param   PHP_ADMIN_VALUE "open_basedir =/home/USERNAME:/home/jail/USERNAME/./home/USERNAME:/tmp:/var/softtmp:/usr/local/cwpsrv/var/services/users:/usr/local/cwpsrv/var/services/user_files/modules:/usr/local/cwpsrv/var/services/twig:";


!!! Make backup of the file before any modifications and fix values.

3. Restart cwp if you modified some files:

Code: [Select]

service cwp-phpfpm restart
service cwpsrv restart
service cwpsrv-phpfpm restart
