Short Code Stopped Working

We use this short code
[listings taxonomy=”status” term=”active” limit=”10″ columns=”3″]

on this page http://webuyhouses-stlouis.com/investment-deals-2/

It’s been working fine until today – it no longer displays properties.
I’ve tried updating the theme, I’ve tried re-saving all the listings, I’ve refreshed the permalinks…. nothing has made it start working again.
