With a shared hosting web company, running on Linux based web server. Sites occasionly goes down with the aforementioned error being the most prolific error showing in the logs.
The site goes down for 2-3 hours before working again. During this time all calls to a PHP file stall for 60 seconds before getting an Error 500 message. (html, css and images work fine).
Even simple PHP scripts that contain NO php code don't work.
Spoke to web host (useless tech support, sigh) who are adament that the error is on my side - somehow. they claim other sites on the server are working fine. makes no sense since NO php codes work, even a php script that contains no php code.
Thanks in advance.
