There has been a fair amount of discussion on this(especially by me
). I still can't seem to put my finger on the reason. The only thing I have figured out is that SOMETIMES, if you shorten the response, it will post(I tend to write long answers to cover a lot of info, and that can cause the message)
I tried using a different browser(as suggested by another member), but it didn't help(I generally use Google Chrome, but tried Microsoft Edge)
