Where your name is displayed to the left, on the same line to the far right you should see a number which I believe is the post number. next to that should be a symbol that resembles a pencil/pen. Click that to edit posts.

Might be a bit of a stupid question but how do you go back and edit a post.

It has been an issue for a number of months now, still no signs of when or if it will be fixed. The error still shows but as you said, they do sometimes succeed. Keep posts short then edit the post to include more information seems to be the work around so far.

This message everytime I post.
Anyone else?
It's been happening for over a month.
It always comes up with the error. But does occasionally post.
Any idea of when this might be fixed?

Thanks
