How do I increase PHP limits?

Overview

PHP limits control how much resources your website can use, such as memory, upload size, and execution time. Increasing these limits can help fix issues with large uploads, plugins, or slow scripts.

Step-by-Step Guide

Log in to your DirectAdmin control panel

Go to Account Manager

Click PHP Settings or Select PHP Version (depending on your setup)

Locate the PHP options or “php.ini settings”

Adjust the following values as needed:

memory_limit upload_max_filesize post_max_size max_execution_time

Save your changes

Recommended Settings (typical WordPress sites)

memory_limit: 256M upload_max_filesize: 64M or higher post_max_size: 64M or higher max_execution_time: 120–300

Important Notes

Setting limits too high may affect server performance Some hosting plans may restrict maximum values Changes may take a few minutes to apply You may need to clear cache after updating settings

Common Issues & Fixes
