The issue is resolved now. djensen has informed me, that he freed up some space.
I have already tested it, and new savegames will be uploaded to the forum correctly as well as downloaded to the user’s harddrive.
Enjoy gaming :-)
When trying to open a Play By forum game, I am not able to load the game. I get this error:

It happens when trying to load an existing PBF save file or starting a new PBF game. This did not happen yesterday.
When I try to open the save file in Local or Play By Email, it loads just fine. Just not with PBF.
Is this a TripleA error or does it have to do with the A&A forum?
@VictoryFirst I can reproduce the issue with current and legacy versions of TripleA.
So I am quite sure that it is related to recent changes to the website/forum.
Let us ping @djensen for further insights.
@VictoryFirst I’m having this same problem. Can’t post my last turn to forum.
“Under Attack Mode” for the bot filtering also causes problems with TripleA.
However, I just created a new rule that will allow TripleA versions 2.6 and later to work properly on the site. I did a smoke test and I think it should work. Please try it.
