XF 2.0 Unable to access post pages within a thread.

[Darcness]

Any time I attempt to access posts beyond the first page, I receive a 303 redirect back to the thread main. For example, if I go to any 'page' off of a thread (http://example.com/forum/index.php?threads/my-test-thread.356/page-2) I get a 303 error and am redirected back to the main thread (http://example.com/forum/index.php?threads/my-test-thread.356/). This happens even for threads with hundreds of posts (which would definitely have a 'page 2'). It happens when I click the 'Next' button or select any page number in the page list at the top as well.

Additional information:

• XenForo 2.0.9
• No installed Addons
• No outdated templates
• No Custom styles
• The issue is experienced by all users.
• This behavior occurs with no browser add-ons installed (Incognito Mode in Chrome)
• No errors appear in the ACP Error log
• I am unable to reproduce the problem here on the XenForo.com

What’s in your htaccess file?

        #RewriteBase /forum

        RewriteCond %{REQUEST_FILENAME} -f [OR]
        RewriteCond %{REQUEST_FILENAME} -l [OR]
        RewriteCond %{REQUEST_FILENAME} -d
        RewriteRule ^.*$ - [NC,L]
        RewriteRule ^(data/|js/|styles/|install/|favicon\.ico|crossdomain\.xml|robots\.txt) - [NC,L]
        RewriteRule ^.*$ index.php [NC,L]
</IfModule>

I tried changing the RewriteEngine to 'On' and it didn't help.

Found the problem. There was some database corruption that caused the position column in xf_post to end up all 0's, so the Thread controller kept thinking that we were trying to view the first post no matter what page we were trying to access. Manually fixing the data repaired the issue.
