Giving me a 403 Forbidden message, which is quite strange.

Hello,

re:1. Please try to re-generate your sitemap

re:2. there is a conflict with your "goto new post" URL format and thread title, please try to redefine url format to:
[forum_title]/new-post-[thread_id]-[thread_title].html

are you talking about this one 'Newest Post in Thread' Redirect URL Format

or another one? because there is none with this heading "goto new post"

because if thats the case mine is already on [forum_title]/[thread_id]-[thread_title]-new-post.html

are you talking about this one 'Newest Post in Thread' Redirect URL Format

Yes, that is correct.
