I've recently wanted to a bit more security to my forum. So, trying to execute this I have tried to password protect my admin directory using the .htaccess file and a .htpasswd file. I followed the rules from this resource (http://xenforo.com/community/resour...and-the-install-directory-using-htaccess.353/), tried to access my admin.php file, entered the usernameassword required and bam! Internal server error.
If anyone could help me out, it'd be much appreciated.
