I noticed during a recent WordPress upgrade, the Democracy Plugin started adding an extra "n" each time you saved the post:

Here's how to fix the problem:

(1) With a text editor, open "democracy.php" – it's located in the democracy subfolder in the plugin folder.

(2) Locate the line below (around line number 331):

return preg_replace('/{democracy[\w\W\s^}]*?}/', '\n<div>\\0</div>', $content);

(3) Change the last set of single quotes into double quotes:

return preg_replace('/{democracy[\w\W\s^}]*?}/', "\n<div>\\0</div>", $content);

That's it. That should take care of the Democracy Plugin's extra n problem.
