It looks like we’ve got the MDC wiki’s errors fixed. It turns out that one of the databases used to store settings had gotten corrupted. After IT repaired the database, I was able to go in and re-apply the settings that were lost due to the corruption. After doing that, and a wiki daemon restart, the site appears to be fully operational again.
If you happen to see any problems, please let me know, and I’ll take a look!
Now that that’s fixed, I’m going to return to driving us toward upgrading to MindTouch 2010 so we can hopefully pick up the supposed stability improvements there.
