In wordpress, you may face PHP memory limit error and encounter following error,
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2348617 bytes) in /home4/xxxxxx/public_html/wp-includes/plugin.php on line xxx
Such error is due to PHP Memory Limit set by the host, this value is set in server’s php.ini file . You can overcome this issue by,
- Increasing the limit via php.ini file
You can directly increase the PHP Memory Limit if you’ve access to the php.ini file. With some hosts, you may not have access to php.ini , in that case ask your host to copy php.ini file to your public_html folder or respective folder where wordpress is installed or you can create a file called php.ini. It can be set by editing value as
memory_limit = 64M
You can change the value as per your requirement.
- Changing PHP memory limit in wp-config.php
If you don’t have access to php.ini file, alternative value can be set in wp-config.php. You need to edit wp-config.php and add following line after the <?php tag
define(‘WP_MEMORY_LIMIT’, ’64M’);
save the file and check.
- Modification of the .htaccess file
This is alternative way, a very simple one. You need to set proper value by editing .htaccess file as below.
php_value memory_limit 64M
- Setting php memory value in install.php
This is yet another way to increase the PHP Memory Limit of your WordPress. There is an install.php file in the wp-admin folder of the WordPress installation.
All you should do is just add the command ini_set(‘memory_limit’,’64M’)in the install.php file. You will see the PHP Memory Limit increased.
- Installing a wordpress plugin
If all above steps are not working, you can try installing proper wordpress plugin which monitors the memory usage or adds proper value in wp-config.php file (with 256MB limit) automatically and no need to edit the php file or set memory limit any where. Just install and activate it.
