 * Hi,
 * I manage the following website.
 * Sometimes I got the fatal errors messages:
 * **_Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate
   20480 bytes) in /home/fondatio/public\_html/wp-includes/pomo/mo.php on line 328_**
 * **_Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate
   20480 bytes) in /home/fondatio/public\_html/wp-includes/class-wp-fatal-error-
   handler.php on line 74_**
 * **_Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate
   528384 bytes) in /home/fondatio/public\_html/wp-settings.php on line 453_**
 * **_Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate
   135168 bytes) in /home/fondatio/public\_html/wp-includes/pomo/streams.php on 
   line 127_**
 * One day, I raised the memory limit, but I got this:
 * **_Notice: Constant WP\_MEMORY\_LIMIT already defined in /home/fondatio/public\
   _html/wp-config.php on line 100_**
 * What are the solutions about this problem ?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwp-includes-fatal-errors%2F%3Foutput_format%3Dmd&locale=en_US)

 * How did you try to raise the memory size? What’s on line 100 of wp-config.php?
   And are there other memory related defines set there?

 * I edited wp-config.php by putting: **_ini\_set(‘memory\_limit’,’512M’);_**

 * Try check these files:
 * user.ini, php.ini, .htaccess, wp-config.php
 * make sure you only use 1 memory limit rule then adjust them to the highest possible
