I understand this may be more of an all-encompassing Wordpress question, but I'm posting here because I only use thematic to build my Wordpress websites and everyone here seems to be very knowledgeable -- so here it goes.
I have created a custom wordpress theme (with thematic) to create a Facebook application. All is fine. However, I would like to create a Fangate for this application. The fangate that I've used in the past works great with non-Wordpress applications (https://github.com/Maggo/fb-fangate).
Here is my issue, the fangate page must be the first file that is opened (index.php). However, as we all know, Wordpress runs off of 'index.php'. I used .htaccess and 'DirectoryIndex fangate.php' to have the fangate run and not have to touch wordpress' 'index.php' file. Everything works fine, except now I am unable to go to my Wordpress dashboard. It just looks like a linux list of files (it looks like this: http://bit.ly/LEiA9k). Does anyone have any good recommendations on how I should go about this? I tried a Wordpress Plugin called Facebook Tab Manager, but it doesn't do what I need it to do.
Is there maybe a way to change the name of Wordpress' 'index.php' file using a function or something?
