Problem with some links from the CMS

Hey guys,

I've recently poster an article via the CMS in which I linked to 2 threads from the forum. Everything worked ok for me but many users reported that upon clicking on those 2 links, Chrome will open a blank page and instead of a http://site.com address in the address bar, the following will appear: vb:showthread/t=575 or vb:showthread/t=577 for the other link. My fear is that this is a vBseo thing, but I can't be sure since I can't replicate this problem on my machine. Also, it's the first time I encountered this problem.

Any advices?

edit: found 2 errors in my error_log (apache)

Code:

[Mon Dec 12 02:01:13 2011] [error] [client 71.231.26.35] File does not exist: /home/swtor/public_html/clientscript/ckeditor/plugins/vblink, referer: http://www.oldrepublic.net/content.php?r=270-Datacrons-What-are-they-and-how-to-get-them-(locations)

Code:

[Mon Dec 12 02:09:06 2011] [error] [client 68.151.59.10] PHP Warning:  mysqli_get_server_info() [<a href='function.mysqli-get-server-info'>function.mysqli-get-server-info</a>]: invalid object or resource mysqli\n in /home/swtor/public_html/vbseo/includes/functions_vbseo_db.php on line 135, referer: http://www.oldrepublic.net/forum/

the first error is exactly from that article

I've opened a ticket at vb.com and they said and I quote: "This is almost certainly a vBSEO problem."

Update on issue : After assisting Cezar within support ticket he issue seems to be related to vBulletin.
