# Wordpress - Allowed memory size of bytes exhausted tried to allocate...

If you are getting **Exhausted Memory Size** on the Wordpress application, regardless that you have configured your PHP Memory higher and PHPinfo-page is showing correct Memory Size, you may need to expand the default WordPress memory limits.

## Expand the default WordPress memory limits

To do that you will need to edit the **default-constants.php** file contained under the Wordpress root directory's wp-includes folder **(/wp-includes/default-constants.php)**:

1. Login to your Cpanel.
