I attempted to use it on my forums but the only thing that would load after implementing it is a white page. I think it was a log file that displayed the error was on the last line of the block of code.

I am also getting sitemap issues
Forum installed in example.com/f/
Meaning posts would be example.com/f/category/post
All links in sitemap point to example.com/category/post

I should point out I'm using the current dev branch.
