CWP-Control Web Panel 500 Internal server Error/Expired/White blank screen - FIX

This tutorial was created at the user’s request. Today, we’ll fix CWP GUI access, like when your server failed to update CWP, or you have a too strict firewall, and it's blocking the CWP update server, and you’re getting a white blank page with an expired message in the log, or even a 500 Internal Server Error for CWP-admin and CWP-user. This is easy to fix from now on, just follow the steps below one by one.

For Centos7/Centos 8 stream/AlmaLinux/RockyLinux/OracleLinux/EL7/EL8 CWP-Admin :

chattr -i -R /usr/local/cwpsrv/htdocs/admin/
cd /usr/local/cwpsrv/htdocs
wget static.cdn-cwp.com/files/cwp/el7/cwp-el7-0.9.8.1224.zip
unzip -o -q cwp-el7-0.9.8.1224.zip
rm -f cwp-el7-0.9.8.1224.zip

For Centos7/Centos 8 stream/AlmaLinux/RockyLinux/OracleLinux/EL7/EL8 CWP-User :

chattr -i -R /usr/local/cwpsrv/var/services/
cd /usr/local/cwpsrv/var/services/
wget static.cdn-cwp.com/files/cwp/el7/cwp-services.zip
unzip -o -q cwp-services.zip
rm -f cwp-services.zip

After you’ve run the commands, the next step is to update the CWP Server :

sh /scripts/update_cwp

That’s it, CWP will be fixed now and you will be able to access the GUI for Admin and User.
