If there is a memory limit error, we recommend upgrading to 64 MB of memory (which should be enough) but 128 MB of memory is even better. It depends if the host can offer 128 MB of memory or not. Upgrading to 64 MB of memory should be enough.
You can change the line in PHP.ini if you have access to your PHP.ini file.
If your line shows 32M try 64M or even 128M:
memory_limit = 64M ;
Maximum amount of memory a script may consume (64MB) If you don’t have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 64M
Try adding this line to your wp-config.php file: Increasing memory allocated to PHP
If you are not sure how to go about this, we recommend you contact your hosting provider and give them the information explained above. They should know how to apply this upgrade for you.
The memory limit error should be resolved once that is upgraded on the server.
