I've been running HG on a Raspberry Pi for a couple of weeks. It worked well, but the web pages were slow to load. I decided to run it on a faster computer so the interface would be snappier. I installed r370 on a server running Ubuntu 12.04.4. It appears to have installed successfully, but when I go to the Configure | Automation page, all the groups are empty. What would cause my initial configuration to be messed up this way? I tried uninstalling and reinstalling, but I got the same result.
