If your site is having memory limit issues, you may be able to adjust this yourself – or, you may need to speak with your host. To adjust it on your own, here are some things you can try:
1. Edit your wp-config.php file.
Add this to the very bottom, right before the line that says, “Happy Blogging”:
WordPress memory can be different from the server – you need to set this regardless of server memory settings
2. Edit your PHP.ini file.
If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 64M try 256M:
memory_limit = 256M ; Maximum amount of memory a script may consume (64MB)
3. Edit your .htaccess file.
If you don’t have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 256M
4. If none of the above works then you would need to talk to your host about having them increase your memory limit.
