How to fix Fatal Error out of Memory WordPress?
1. You might find some redundant php.ini files so try looking for the php.ini file. Make sure you have the one which is actually being read by PHP. Just to make sure, create a new php file in your root folder, say “check.php” and have phpInfo(); within the php open and close tags. Execute this file to get the information on where the php.ini is residing. Normally it will be in /usr/local/lib/php.ini
Open the php.ini file in a text editor like TextPad (not in Notepad) and change the values for memory_limit. By default you should see memory_limit = 8M. Try changing it to 12M. If it doesn’t work, increase it to 16M or even 24M and so forth.
2. If you can’t find the php.ini file or can’t access to it, then open up the file which was throwing the error and add a line below just after ini_set(’memory_limit’, ‘12M’);
3. You can even consider adding a line in .htaccess file which will resolve the issue.
php_value memory_limit 32M
4. Or else, Try adding this line to your wp-config.php file:
