I will be rolling out EzIRC 2.0.2 sometime soon. I'm not 100% sure yet if the usergroup permissions are the same in vB4 as they were in vB3, but I'll find out. For a temporary fix, you can edit the ezirc.php file, and find "global.php"
After that line (meaning the entire "require("global.php")" line or whatever it is, add:
PHP Code:
if($show['guest']) { print_no_permission(); }
This will disallow guests from viewing the ezirc.php file
