It's always a good idea to keep PHP updated to the latest version for security updates and improved performance.

Go to your TsoHost Client Area: https://my.tsohost.com/clientarea.php Go to Services. Click on My Services. Select the cPanel service in question. Click on the Login to cPanel button. Click on the cPanel Admin button.

Once you are in cPanel navigate to the Select PHP Version option.

Select another PHP version by clicking on 7.x (current) then click on Set as current.

Note: It is recommended to double-check the files of your website if they are supported with the new PHP version with the help of a developer as changing this might cause incompatibility.
