Thanks for reporting this, Rod. There were a few other digihitchers who filled out a bug report at the top of the page about this, but I just caught it a few hours ago.
We did a major upgrade to the digihitch database earlier tonight. MySQL was upgraded to version 5.x and it "broke" one of our important topic queries. Just had to tweak a "left join" statement. (Yes, TMI for many of you... that info is for the geeks among us.)
Let us know if you find any other bugs due to the upgrade. You can use the quick bug report form at the top of most digihitch pages.
