Hi I ran into the same thing on the 10th of november and the guys helped me on the freenode irc #weblocks channel. There were various suggestions and in the end I got poor leslie to try and explain the whys and wherefores of the whole issue. I will not attempt relaying the information because I will inevatably get it wrong on some level.
I dont know if there is a online archive of the logs some where, but if you want I can send you the log(s) of the discussion(s). There are a couple of paste bins and other threads mentioned in the discussion that also helps.
