I understand they’re working on it. The temporary fix is to delete apostrophes and quotation marks from text that has been copied and then type them back in.
What you can do is copy the text to Notepad and do a Change All.
Also, judicious use of the "Preview" button. When I quoted your post, it messed up your apostrophe. I had to fix it.
But why are you picking on this poster for a problem everyone posting at FR is experiencing? He’s free to add to the caption as others do, without having to correct an error that’s within the FR system. Thread after thread after thread contains the same problem without everyone fixing it.
Has anybody tried pasting articles into Notepad so that they become plain text and then pasting into FR?
