I just upgraded from WordPress 2.0.5 to 2.1, and a few things broke. (Most notably, the blogroll). I’m working on getting it recovered.
If you notice any other obvious errors, please let me know.
….In the blog software…. not the LOST theories. 😉
Things are pretty much fixed; You won’t be seeing any PHP or SQL messages (I think).
The Site Links and Blogroll got rolled together when the upgrade happened. I’ll look into fixing the rest soon.
