You configure the options for this addon in your AdminCP. Then expand "vBulletin Options" on teh left, the click the "vBulletin Options" sub-menu on teh left, then on teh right pane double click on "Different Domain, Different Style" and set the options accordingly

I apologize to bother you
I am not exactly setting how to configure
I am attaching a screen shot
after entering vbulletin options I am not finding different domain different styles

It will likely be right at the end of the list....

How do you get different styles to show different forums?

e.g. Site 1.com has Category A and B
Site 2.com has Category C and D

Thanks in advanced.

I'm not the license police, but to do that you would require multiple licenses of vbulletin.

This addon can not do that, but it could probably be done with template conditionals

will it be under showforum?

in my sandbox.motorolafans.com, it shows everything propey, even in forum main, but if u go to any forum or thread, it can't detect css, or rather, it can, but doesn't show.

what makes?

Looking at the source to your site, the CSS path is relative. With the url re-writes the css fiule does not exist at the relative path when in any forum other than the forumhome

An immediate test/work around would be to edit your vbulletin options and select "No" to "Store CSS Stylesheets as Files?"

Great! That fixed it! Thanks alot!

are there anyone with login problems?

I let 2 domains point to the same place, but one's logged in while the other's not. is there a way out here?
