On 02 December 2018 the server we're operating from are shutting down PHP 5.6.
The new PHP 7.0 (7.1 - 7.2 - ....etc) would be the lowest PHP standard.
This site is tested for PHP 7.0 and should work well.
The question that remain is; what will happen with the forums?
As of August 2018 the SMF sofware is buggy.
Escpecially "Sessions" is affected. Meaning that log in/out might crash.
Also posting in forum threads is buggy as of now.
Hopefully, the SMF team will have ironed out the bugs by December.
(We're now operating on PHP 5.6 until further notice)
