Thanks for your reply. I have tried but the default Like button does not work. I do not know the reason.

If its a custom style you should try it against the default style.

Obviously make sure the thread is guest viewable.

If still not working try disabling other mods to see if a conflict.

Mine appears on the top of the page, but for some reason when I click it, it does nothing. It's weird because when I "Like" something, my website name appears on my facebook, and it says "Dave234 Likes This" on my website.

but when I click the "Connect" button at the top of my website, it does nothing.

Mine wasn't displaying at all... The connect button. I rewrote some things and got it to display, but clicking it just resulted in me being sent home.

works on vb 420..??

thanks

Yes, you can see it in action on 4.2.0 at the demo site: http://www.qapla.com/mods/

I've installed it, you can see it here at the bottom of my forum: http://www.gamerperfection.com/forum.php but there is no Facebook button.

I have enabled facebook option in admincp > options. I didn't put an application ID because well i don't have an application. So why would facebook not be appearing?

Apparently you need an Application ID these days for it to show.

So it won't work unless i create an application which I have no idea of how to do?

In Facebook Options (vbulletin settings) there is a link in the text description of the Application iD setting - http://www.facebook.com/developers/

Basically tells you what to do, not hard.
