We have our Joomla setup with a .htaccess file to allow only particular IP addresses to hit our administrator area. We have several users all over the country who can access it just fine. I have added a couple of more IP addresses in the file and saved it but for these new IP addresses they are unable to get to the admin login screen. It still says 403 forbidden.
Is there a service or a cache that needs to be cleaned out for this to work properly?
