OK, maybe the post title is slightly over-dramatic but I had an interesting problem with the Bad Behavior Wordpress spam-blocking plug-in today.

When I logged into Wordpress I got the following page:

Error 403

I was slightly nervous on seeing this as we had a brief intrusion at one of our other web sites recently and I imagined the worst. However, it turns out to have been a problem with the otherwise excellent Bad Behavior plug-in itself. See Michael Hampton’s post on this and get yourself a copy of Bad Behavior 2.0.11 to fix the problem.
