All you have to do to get your website up and running on PHP version 7.2 is select the version and save the change in the control panel.
There could be minor issues, but so far this version is even better than the 7.1 version.
A small note to you developers:
mcrypt is no longer available in this php package. The mcrypt project has been dead for over 10 years and is now no longer supported.
If you have any questions relating to this or just out of curiousity, please contact us, our system engineers wil gladly help you in any way they can.
With Kind regards
