A big problem surfaced after I updated the site a couple weeks ago. People were getting 404 errors when trying to send updates or add new breweries. (This would explain why I didn't receive many updates while I was in Germany.)
The problem was a file that didn't make the jump from the old site to the new site. I've installed that file and it looks like it's fixed now.
Thanks to Ralph Wells, Mario Kornmesser, and Robert Sizemore for letting me know!
