Problem: With BotBanish 3.2.01, BotBanish will show a blank screen.
Solution: Solution is to place a file named "favicon.ico" file in the root folder. The browser generates an ERRORDOC error when this file does not exist and since BotBanish is handling the generated ERRORDOC errors the user would be treated a a foreign entity that should not be allowed access to the system thus generating a blank screen. The favicon.ico file is the icon file that is displayed in the browser tab for your site.
Another thing to look for is a file titled error.log in any folder. This file logs coding errors and can help find the problem.
