Ask your host to increase the available memory limit
My client contacted Uber support and they increased the available memory to 256MB. I tested with phpinfo.php and the memory_limit parameter was set at 256M. Unfortunately the ‘Fatal error: Allowed memory size of 67108864 bytes exhausted …’ error was still evident when trying to activate plugins.
Try to increase WordPress memory via wp-config
The next attempt at increasing the memory available for WordPress scripts was to increase memory in the wp-config.php file via adding
define( 'WP_MEMORY_LIMIT', '256M' ); before the wp-settings.php inclusion.
And still the ‘Fatal error’ message appeared.
How to increase WordPress memory using PHP.ini
Next step, and the one that resolved the memory issues, was to add a php.ini file to the wp-admin directory on the server. Here are instructions to increasing the memory that proved to work on Uber Global hosting (and usually works on Crazydomains hosting too):
- Using a text editor, create a file called php.ini
- Save the following to the php.ini file:
memory_limit = 256M
- Using FTP (or the File Manager in cPanel), copy the newly created php.ini to the wp-admin folder on your host server.
The WordPress memory issues should now be resolved.
