WordPress “Allowed memory size” on wp-db.php [closed]

You need to increase the php-memory-limit you can find out how much you have now with <?php phpinfo(); ?>

Edit php.ini .Search “memory_limit” in your php.ini, and change the value of it. If no “memory_limit” found, add the following line at the end of php.ini
memory_limit = 128M ; /* Change the 128M to your needs */
Save file.

Edit : Or try in your wp-config.php, find or add the following line: define(‘WP_MEMORY_LIMIT’, ’64M’);
