Increase PHP Memory Limit in CyberPanel

After Installing CyberPanel, many configurations come with their default values. For example, memory_limit, upload_max_filesize, and post_max_size come with their predefined values. Sometimes we need different configurations or values according to our website needs. We can easily change or adjust these configurations and values right from the CyberPanel dashboard with some tweaks.

Check below to properly adjust these predefined configurations:

Edit PHP Configurations in CyberPanel

To edit PHP configurations, log in to your CyberPanel dashboard using the 8090 port. On the right side of your screen, scroll down the page and find PHP

Click on PHP and select Edit PHP Configs from dropdown. On the next page, under Basic select PHP version that you want to edit. We recommend use PHP 7.4 that is fast and stable at this moment.
