It looks like the fix discussed in
https://www.axisandallies.org/forums/topic/37967/triplea-posting-to-forum-currently-does-not-work
will resolve your issue, too.
After having posted a game-save to the forum and clicking “done” the client (2.1) still asks me if I’m sure I don’t want to post. This is slightly annoying and I sometimes have to go back and check that it really did post, so I don’t start to swamp the threads.
It didn’t do this in the earlier versions I’ve used.
As this issue needs to be addressed to and resolved by the developers - there is nothing we can do from our side here - I would kindly ask you to report it folllowing this:
