Facebook Like Button Error - The href URL must be absolute

To fix go to the Admin CP -> Plugins & Products -> Add New Plugin

Product: vBulletin
Hook: fb_like_button
Title: Facebook Like Fix

PHP Code:

if ($show['fb_likebutton'] AND (is_browser('ie') || is_browser('opera')))
{
   $templater->register('href', get_fbcanonicalurl());
}

Set "Active" to YES and SAVE.

The error should go away.

This is because Facebook changed how the like button should work.

The fix worked - and thought I would share so others can solve the issue.

Anyone?

Fresh install of 4.2.1 last week. Facebook like button was working fine. Today I'm getting an RED error and a popup that says "The href URL must be absolute"

I noticed this was a problem in the past but was fixed in 4.2 and like I said - was working a day ago.

Might Facebook's tinkering today have caused the implementation to fail again?

Anyone else having the issue?
