How to change the PHP version on your domain using cPanel?
Some software requires an older version of PHP like 5.6 while others ask for PHP 7. If it happens, you need either of the versions. You can switch to it from cPanel.
1. Log into your cPanel account.
2. In the Software section, click on the MultiPHP Manager Icon.
3. Scroll down to the bottom of the page, select your domain from the left side of the screen, and see an option PHP Version with a drop-down menu on the right side. Please select the appropriate PHP version from it and click the Apply button.
It will take a few seconds, and then your PHP version will change to your selected version.
