If you wish to reset the PHP version to the default version, follow these instructions:
- Log into your cPanel account.
- In the "Software" section, click on the "MultiPHP Manager" icon.

- Scroll down to the bottom of the page, select your domain from the list on the left, and locate the "PHP Version" option with a drop-down menu on the right. From the drop-down, select the "inherit" option and click the Apply button.

It may take a few seconds for the changes to take effect. Once complete, your PHP version will be reset to the default version for your hosting account.
