We usually offer several PHP versions on our UNIX platform.
You choose your preferred PHP version yourself in Loopia Customer zone by clicking on the domain and then choose “Website at Loopia” > “Unix”. Select your preferred PHP version and press “Save”.
All PHP versions run on servers with Apache 2.4.
Internal Server Error
From PHP version 7.1, we do not have backward compatibility with outdated code in htaccess files. This means that allow/deny commands and AddOutputFilterByType will not work when you change PHP version to 7.1 or a later version. If you have these rows in your htaccess file, you might get Internal Server Error on your page. Then switch to PHP version 7.0 in your Customer zone and remove these rows in your htaccess file via FTP.
