I've used AAPP for quite some time and I upgrade regularly. Since yesterday I'm on 3.5.1. Since a few upgrades ago I have no configuration screen. This doesn't matter since I don't have to change anything, but should I or should I be curious about new functions, this could be helpfull. The 'configuration screen' only says:
NOTE: This is an incredibly powerful plugin that modifies your server not wordpress. This can easily take your site down. If you experience a bad error, delete the .htaccess files on the server using ftp, ssh, webftp, or contact support, etc..
And further only has out-links (About this plugin, AskApache links and Security articles). The website itself malfunctions (IE6 at work), so I figured I'd make notice of the problem here.
