Love this plug in. But what do I know, in trying to ban a referrer for the first time, I made the mistake of entering the entire url, http://thenameofthesitexxx.com. It caused an internal server error and brought the site down. With the help of my host provider, went into FTP, deleted the plug in and had to rename htaccess. The site went up fine after those measures, so I thought I could just reinstall the plug-in. When I activated it, same thing happened. Internal server error. So had to delete the plug-in again and rename htaccess again. My guess is, somewhere in the site, my error is still in the memory or something. How do I clean this up so I can reinstall the plug-in?
