I have recently tried making an edit to my answer on this post, but, to my surprise, I get a message stating that "An error occurred submitting the edit."
I suspected that it might be a temporary issue with Ask Ubuntu being in "read-only mode," as was the reason for the error in this post, so I waited several hours and tried again. However, the issue was not resolved after waiting.
I then suspected that it might be a problem with the content of the edit to the post, but I still get the error even when I make no changes at all to the post when editing.
I then suspected that it might be that I am unable to edit any answers, but I testing and was able to edit other answers I had made on Ask Ubuntu without any problems.
What else can I try? What could be the cause of the issue?
