In the past few days I noticed all my categories in the pull down menu in my side bar (regardless of hierarchy) are returning a 404 error page and redirecting to ifitshipitshere.com/undefined.
I tried switching permalinks to default from post name and that didn’t change the problem.
Can someone please help me out? I'm not super code savvy.
site is http://www.ifitshipitshere.com and I’m using WordPress 3.8.3 running Radiate theme.
Thanks so much
