Well, of course it doesn't work!
It turns out the when I performed a bug fix a few days ago during testing, I changed too many variable names. The url that you were seeing was pointing to the forum id as the topic id so it obviously wasn't working especially if the forum for that id didn't exist.
Anyhow, I fixed that problem.
SMF SearchBot 1.0.3 BETA has now been released!
You can find it
here.
Man, I hope I get this thing working soon or I'll run out of version numbers before leaving BETA!
If this doesn't fix everyone's problems, please provide a link to your website so I might be able to seee things from your point of view!
