Fatal error: Out of memory (allocated 6291456) (tried to allocate 7680 bytes)
This is usually caused by Wordpress, Drupal or other ridiculously inefficient CMS' out there, as a temporary fix you can increase PHP's memory limit but it's best to find the actual culprit, by disabling add-ons and other scripts etc...
