 * At the urging of the Codex, I hit the switch to go from PHP4 to 5 on hostmonster.
 * The site still works, but am now getting this error when trying to get the to
   admin pages..
 * Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate
   122880 bytes) in %%path removed%%/wp-admin/menu.php on line 82
 * CPanel has no option to switch back to PHP4
 * Am at a bit of a loss now.

 * Here are four ways to increase PHP’s memory allocation:
     
 *     ```
       1. If you have access to your PHP.ini file, change the line in PHP.ini
       If your line shows 32M try 64M:
       memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)
        
       2. If you don't have access to PHP.ini try adding this to an .htaccess file:
       php_value memory_limit 64M
        
       3. Try adding this line to your wp-config.php file:
       Increasing memory allocated to PHP
       define('WP_MEMORY_LIMIT', '64M');
        
       4. Talk to your host.
       ```
