After installing, everything working fine.. Except when we're replying the post
I have the exact same problem. Creating a new topic works fine, but replying, editing, or deleting a post gives me a page with an incorrect link back to the post.
If I make a new post, the redirect url is something like: -http://mysite.com/forum/my-forum/my-topic-t29, which works perfectly.
If I reply to that, the redirect url instead becomes something like -http://mysite.com/forum/post85#p85, which doesn't work. It should be -http://mysite.com/forum/my-forum/my-topic-t29#p85, but for some reason this doesn't work.
I'm running phpbb3, your SEO Ultimate 0.6.2, and your No Duplicate 0.6.2 mod. I'm running in Advanced mode, no sql rewriting, virtual folder, no virtual root, forum url caching, and forum id removing.
Any help would be appreciated.
