 * Hi,
 * I’m trying to install 4.1 … following the install process I enter the MySQL details
   and click for the next step….and get this:
 * `Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate
   138 bytes) in /web/sites/_c/_o/_n/mysite.co.uk/public/www/cp/wp-includes/pomo/
   streams.php on line 71`
 * Any idea what the problem is here?
 * thanks

 * thanks for the tip, Tara.
 * However, there is no ‘define WP_MEMORY_LIMIT’ in the sample config file in the
   4.1 distro.
 * Remember, I can’t complete the install process due to this…. so I haven’t reached
   an admin panel where I can set it 😉

 * If you are doing a manual install you could just add the line
 *     ```
       define('WP_MEMORY_LIMIT', '64M');
       ```
   
 * to the wp-config file or try contacting your host and ask them to increase the
   php memory limit via the php.ini file.

 * thanks, Keith.
 * I have in the meanwhile contacted my host and indeed been directed to the php.
   ini file which I managed to change to 64M… and it worked fine then!
 * That line will be useful to know, though, as I believe that would allow WordPress
   alone to use more memory without having to change allowance for my whole server
   space.
 * Thanks for your help.
