Groupon Causing issues

I logged into an old site that I had setup and saw that there was problems on the Dashboard. I ended up killing that database and starting a new on assuming that there was a problem in the database. After recreating the new database and getting everything setup I went to the site to cause a hit. This one showed up just fine without any issues. A few minutes later, the site was referred to by groupon and the page started having issues again. The only thing that loads is the Visitors in real time. Nothing else works. That’s how I know if is from groupon is because there is my hit and two groupon hits. The other site that I have on this instance is still working just fine. This is on a Server 2008 instance with MySQL.
