I recently updates to WP 3.9.1 and after that updated to the latest YARPP-version. After those updates every single post has shown a BREAK at the bottom of the content (< br >). My first thoughts were that there is an issue with WP 3.9.1 - but after I returned to WP 3.9 I realized that the issue still occours.
So I replaced YARPP with the previous version and voila: The problem was solved.
So your latest YARPP update has an issue that adds a < br > (without spaces of course) at the end of post content.
Could you please fix this?
