How to Modify PHP Memory Limit

Demanding applications like WordPress with WooCommerce or PrestaShop often require higher PHP memory limits. Here is how to configure them:

Method 1: DirectAdmin / cPanel PHP Selector

1. Log in to your hosting control panel.
2. Go to Select PHP Version → Options tab.
3. Locate memory_limit and select your desired value (e.g., 256M, 512M, 1024M).
4. Optionally adjust upload_max_filesize and post_max_size as needed.
5. Settings are applied instantly without server restarts.

Method 2: Custom .user.ini file

Create or edit a .user.ini file in your website's document root (public_html) and add:

memory_limit = 512M
max_execution_time = 300
upload_max_filesize = 64M
post_max_size = 64M
