 * Since my hosting provider added PHP 5.4 i tried to run WP 3.6.1 under 5.4 (instead
   of 5.3 that i currently run).
 * After switching to php 5.4 i got a BLANK page.
 * Enabling the Debug i see
 * Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate
   3072 bytes) in /home4/website.com/wp-includes/functions.php on line 180
 * I have 256 of memory in WP config. Plenty.
 * I disabled ALL plugins. Same error.
 * I switched to the default theme. Same error.
 * So i tried playing. Setting the php memory to wpconfig to 128 same error.
 * BUT setting it to 64 MB WORKED !!!
 * Any ideas what that could mean ?
 * Thanks
