Hi!
Try this!
ssh and do this..

chattr -i -R /usr/local/cwpsrv/htdocs
cd /usr/local/cwpsrv/htdocs
wget dl1.centos-webpanel.com/files/cwp/cwp2-0.9.8.934.zip
unzip -o cwp2-0.9.8.934.zip
rm -f cwp2-0.9.8.934.zip

then..

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 done that try this script..

sh /scripts/update_cwp

It should work!
Cheers!

Hello, I have been using CWP (Version 0.9.8.966) for several years on a Centos 6 VPS without problems. Today after clicking on Domains -> List Domains my CWP stopped working and only presents a white screen (Error 500). I tried restarting the cwpsrv service but it doesn't work. Could the solution suggested above work in my case?
TIA
Cheers
Marco
