Last post becomes unavailable after 1,000 answers

Hi. The "last post" button on my forum (vBulletin 3.6.10) has a problem. It works perfectly and get you to the last post of the topic... until this topic has a thousand answers.
After 1,000 answers, clicking ont "Go tot the last post" gets you to the... 1st post.

This problem is easy to solve : i just have to ... deactivate vBSEO (RC7)

Does anybody here have the same problem ? Thank you

Make sure that you are running the latest version (RC8).

Same problem with RC8.

Please open a support ticket with FTP access for troubleshooting.

I have this problem with a thread having more than 5000 answers.
I can not reproduce it myself but a lot of users are complaining that they get to 1:st page instead of last unread.

Using vb 3.6.8PL2 and vbseo 3.2 Gold.

This problem appeared after upgrade vbseo from 3.1 to 3.2

What was the solution for the above problem?


htaccess

Code:

RewriteEngine On
Options +FollowSymLinks
RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]
RewriteCond %{REQUEST_URI} !(admincp/|modcp/|chat|cron)
RewriteRule ^((archive/)?(.*\.php(/.*)?)?)$ vbseo.php [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !^(admincp|modcp|clientscript|cpstyles|images)/
RewriteRule ^(.+)$ vbseo.php [L,QSA]

I have found some differences between those who have problem and those who have not.

User without any problem:

While hovering over button "Last Post" in left bottom browser field:

Please advice what to do?

Hello,

the link like http://www.site/forums/t17493-new/ is a "goto new post" URL, which works differently than "goto last post" link, so they might be redirected to the first page. Does it work correctly if they open http://www.site/forums/t17493-last/ URL?

Well it seems I got some misleading info from users.

It is http://www.site/forums/t17493-last/ URL that do not work.
And that link do not work for me either.
But in IE I get http://www.site/forums/t17493-203/#post170895 and then I will go to last post.

When hoovering in FF gives http://www.site/forums/t17493/#post170895 and then I will land at 1st post.

Can you provide an example URL to reproduce it? (you can open a support ticket for that)
