I think this is because of your anonymizer hack, because if you look at the link in that thread:
http://www.cpfools.com/forum/showthread.php?t=4281
The actual link is:
http://www.anonym.to/?http://www.cpfools.com/forum/showthread.php?t=4281
Which will mean nothing to the plugin. The plugin will search for the setting you have for Forum URL in your vbsettings and ignore all other URL's. The only way that MIGHT work, and I am not sure is if you change your Forum URL setting to:
http://www.anonym.to/?http://www.cpfools.com/forum
