So lately I've been getting these quite often. Happend before I updated to wp 3.7 (currently running 3.8)
Here's my website http://autoteile-bg.com, Godaddy hosting.
Tried deleting the .htaccess then setting permlinks to default and revert them to how it was before, that didn't help! also tried deactivating all addons, that didnt help either.
Contacted GoDaddy, they said its not their fault and couldnt help me.
Read somewhere on forums that the plugin W3 Total Cache mightve caused it, so I tried getting rid of it. Still the same.
Here's the error logs from today if someone can take a look and help me out id be forever grateful. http://ge.tt/8KU0yXA1?c
