So why would this error show up on every account on a dedicated server, it seems to specifically affect the php files?
Are you using su_php for the handler? If so, it more than likely has to do with permissions. Check your apache error logs.

Ok, thanks for the extra info another way that i found to correct this issue is to recompile apache, it will create about 5min of downtime but works also
