Using mod_ruid2 with LiteSpeed can cause permissions-related issues. If you are running LiteSpeed, you can verify if you are running mod_ruid2 using the httpd -M command.
[root@server ~]# httpd -M | grep 'ruid'

We recommend that you use mod_suexec instead of mod_ruid2. You can change this in the Apache Modules options in the WHM interface "Home / Software / EasyApache 4."
