I have a wordpress MU site, and tried to install your xml site map. I moved the generator folder into the root and set up the other 2 xml files in the root outside of the generator folder. I also set the permissions as noted in the document.
I am getting an odd problem, if I type [external links are visible to admins only] I am getting a page not found error in wordpress. If I put on of the php pages that are inside of my generator folder in the root, I can access them fine. I can also view any other files in the generator folder, just not php files.
I am trying to figure out if this is a problem with wordpress MU or my servers php settings.
I do find it odd that wordpress can be functioning properly since it also has php files located in folders.
Anyone have/had a similar problem, or has any suggestions?
