Hi guys
I don't know where to post this so excuse me for putting it here.
I've had problem to reply for a long time. Basically, here a picture below. 8 out of 10 times I get this error message. I've tried to contact the board administrator, as it suggests, I've done it like 2 or 3 times but I always got no answer.
Perhaps posting it here will help to solve the issue. It happens on both PC (Windows 10) and phone (Android).

No Mod is going to reply to me?

Cannot reply in another thread. This is what I'm getting. It says I'm supposed to contact the administrator, I've done it several times, got no reply via email.

Who solves problems like this here?
