If you’re not sure what is the current memory on your website, you can find out that in the WPZOOM Theme Options page, under the Import/Export > Demo Content section:
How to change the WordPress Memory
The most common solution to this problem is to edit the file “wp-config.php” from your WordPress directory and to add the following line somewhere at the end:

Note: If this solution does not work for you, then this means your web hosting service provider does not allow WordPress to increase PHP memory limit. You will need to ask your web hosting provider to increase your PHP memory limit manually.
