I had added the short code -- [product_categories number="5" columns="4"] -- to the Text widget in the side bar and it worked. Then it stopped working and displays nothing.
I tried some of the other short codes in a blank page. The ones that call a page ('cart', 'my account') work just fine. The others, like the one above, do not work and I can't figure out why. I've tried different templates with the same result.
Then I remembered I had upgraded WP from 3.5.1 to 3.6. Has anyone run into an issue like this before?
