s parameter 2 to be array, null given in /wp-content/plugins/bbpress/includes/common/functions.php on line 1446

This error was appearing on the Forums page under wp-admin in WordPress so naturally I thought this was a bbPress issue.  I fought with this problem for a little while before I was able to find the answer so I figured I’d post my results here.  The solutions that I found while googling did not resolve my issue though they did point me in the right direction.

Ultimately, I ended up deactivating each of my WordPress plugins one at a time until the error went away.  When it did, I found the culprit.  In my case the problem plugin was Popup Maker.  I noticed, however, that there was an update for Popup Maker.  I installed the update (to version 1.4.13) and VOILA!  The error went away.  I hope this helps someone else!
