Increase PHP and WordPress memory limits
Since WordPress memory limit is one of the most common causes for blank pages, we recommend increasing your limit. Indications of this error could be a white screen or an error message like this one:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2348617 bytes) in /home/username/public_html/site1/wp-includes/plugin.php on line xxx
