Yes, we have just finished a feature to redirect urls generated by a different rewrite rule(like TfSEO or C-Logic SEO or any others) to the your currrent url structure. If anyone interested, please contact me. I will do it for a small fee ($10-$30 depending on how many types of url to be redirect).

Yea, vBulletin 4.0 is supporting the Friendly Url Structure for thread, member and forum. But the feature is additional and not be optimized as ours. Anyway, vBulletin is a forum software, putting more focus on forum features, not a single SEO function. For example, vB4(at least beta version on their site) is not
rewriting member list page, faq page, calendar page and showpost page!
rewriting Blog pages, tags page and album pages (as in YABBSEO full version)
converting non-english languages in urls
stripping common words in url, like a, an, and ...
adding nofollows for some type of url as you want in YABBSEO or other similar SEO software
supporting customised SEO url(they provide three types url: showthread.php?tid-title, showthread.php/tid-title and threads/tid-title)

Thanks!
I resolved this problem with replace two php code in version 1.0 (album error)
but :(
i protected my admincp folder! and this error :(( "www.example.com/the401.shtml", can you help me?

You mean you use a custom admincp directory? If yes, you can edit .htaccess file to find
and then replace admincp with your custom admincp directory.

Oh, No!
I said "protected my admincp folder" no rename or new folder!
for this protect, i have this problem, and i don't know what's the problem :(
please help me... :x

Sorry, I could not understand what you mean. Maybe it would be helpful to show me your forum.

ok
I protect my admincp directory!
.htaccess:

Thanks for this :D I installed it yesterday and it works a charm ;) I mucked up the config.php file a few times in trying to make the URLs look nice haha but other than that, it's perfect ^^

It is weird. Are you sure /admincp does exist on your server? What do you mean "I protect my admincp directory!"?

Another suggestion is if you want to rewrite the findlastposter link on forum index page: You can do some configuration in config.php: change post_parseurl to 1.
This means YABBSEO script will query database to get the corresponding userid(or post id,thread id) for the "nonparsed" links by default. BUT you should have in maind this will use additional mysql queries. If your forum is overloading, it is better to disable this option.

P.S. with YABBSEO lite edition, you could not remove our copyright information from the footer.
