Facebook Error: Facebook Only Allows Single Blank Lines in Post Text
Sometimes you will see an error about how many blank lines are in your Facebook post.
When this error occurs, it is likely that you may have written a post with 2+ blank lines, which, if published on Facebook, Facebook will compress to show 1 blank line.
This is due to Facebook's formatting rules, you'll find that the same thing happens if you type a post with 2+ blank lines in Facebook directly.
The notification you've received is a warning to let you know that your post won't appear the way you've typed it, SmarterQueue will remove the line breaks to give an accurate preview.
