Could not fetch current configuration. Error message: [Errno 13] Permission denied: u’/usr/local/lsws/conf/vhosts/domain.com/vhost.conf’

i have changed user group with “lsadm” but no luck.

anyone can help me?

Which version is this? (looks very old)

version 1.6 build 1.

I didn’t update Cyberpanel, only openlitespeed.
Because I was worried there was a problem.
