no advanced search
Trying to find a post older than 1 year, but advanced search is not showing up running Firefox.
There's a bug with search displays currently, which was described here. Hopefully this will be fixed early this week.
But despite this, you still should be able to do advanced searches. I just tried it out in Firefox, and it seems to be working fine, so if you're still having problems, it would be great to get a more specific description of what is happening.
