Looks like my MLS did something with the listings data file that made updates fail over the last couple of days. I manually updated the New Listing and Price Change reports a few hours ago. The New Listings report is still having problems when you click on a MLS # on listings since Friday. This should all be fixed when the other vendors that I use for the MLS searches do their daily updates early tomorrow morning.
8/3 update: The new listing report looks happy again 🙂
