lajuana,
I’ve just committed version 1.0.1 which has a bug fix for the problem you’ve described.
The redirect loop was occurring under conditions where the block list was loading up blank values which caused a global match of any domain name on affected systems.
I would appreciate if you would please give my plugin one more test using the newest version (1.0.1) and provide me with any feedback you may have. If you feel the plugin is working properly and is suitable to your needs I would appreciate it if you would please revise your rating based on the successful resolution.
