Server Requirements

Server requirements on the following page state PHP >= 5.5.9, MySQL and MCrypt:

This splendid app also requires the proc_open function is not disabled in php.ini.

Does anyone or Hillel know if there are other requirements, particularly with respect to PHP functions please?

Many thanks in advance.

FYI… we’ve heard from users that upgrading to PHP 7 removes the requirement for proc_open.
