Someone else's? It takes the visitor to a webpage
of the developers
of the Bad Behavior extension you yourself installed. (The domain
http://www.ioerror.us belongs to them.
Ah, should have checked that.
But something doesn't make sense here. I was able to log into the wiki
fine several times after installing Bad Behavior. Why would it suddenly
start working this way?
Have you really thoroughly studied the instructions
Hopefully I'll be able to figure it out from there, because I really need
spam protection on that wiki. :-/
