Hey Michael,
Thanks for reaching out!
We have some known issues with our ticketing plugins in PHP7 at this time, but most of our add-ons have been tested in PHP7 and should be compatible. I cannot guarantee that there aren’t any bugs, but I have searched for bugs in our development system and, like I mentioned, there are only a few logged and they pertain to our ticketing plugins.
If you proceed with PHP7 and run into any issues, please let me know!
Sincerely,
George
