I cannot see any posts discussing this.
I get quite regularly issues opening the forum or posting replies an "Internal Server Error", error code 500, a generic error message.
Possibly these are server loading issues, and I have often found it quite slow to initially open the forum.
Things are working ok, it is just sometimes I get the error posting and have to re-post again or check if the post actually did work.
I doubt it matters, but I am running Window 10 (32 bit), fully updated using the latest version of FireFox as my primary browser, and running the free version of AVG Antivirus.
