Hi
I read this yesterday and had a little think overnight
Richard confirmed host corrected issue in Apache however, it may not be the issue causing this
It could also be an update to distro/cPanel/easyapache which has overwritten the change or other code which stops the change (sorry, we do not use cPanel on shared hosting)
I am leaning towards it is not resource running out
The easiest way forward, given that time stamps are been posted, is to look at the logs and see if any requests are shown within say 1 minute (+ or -) of the time stamps posted (due to time differences on different computers)
As posted earlier, same applies, no requests, update support ticket or open new support ticket, if requests are shown, look at website code
Lastly, it could be a blip I suppose, but due to the nature of the issue, in that it is intermittent and no time repeatable i.e. Say happens on the hour or 8am etc... so this could take a little time before it is fully resolved
Many thanks
John
