Small issue, URL re-writes half working?

Basically it's this..

If I'm on my forum home page and click the top most recent last post, it gives me a link of..

.....legionofsteel.org/forums/showthread.php4?p=207850#post207850

But when I go to the 'section' it's in, as with the top one being in the general section of my forums, then proceed to click on the post (the same thread as above) it gives me the..

.....legionofsteel.org/forums/general/9781-gray-belt.html

Does anyone know why on the main page it uses the original url format, then if I click on the section it's in, and then click on the thread link it properly shows the seo'd url? I'm thinking it's just a small adjustment somewhere?

Please try updating the following for vBSEO 3.2.0, within the config_vbseo.php file:

PHP Code:

define('VBSEO_VB_EXT', 'php4');

I looked and it's already changed to php4, hmmm.. I wonder what it could be.

It only does this with last post links? Everything else is working fine?
