BEFORE STARTING: you will notice that we only support OpenSSL 1.0.x – this is because the game client uses RC4. OpenSSL 1.1.x removes RC4 (deprecated in 1.1.0 and above). This is a constant we cannot change.
You will need MySQL Strict Mode to be disabled (specially if you use mysql 5.7).
If you still have problems, you can try to ask help on IRC, but remember it's not real time 24/7 support, most of people there lives on GMT and they can be sleeping or working.
