Hi Otto, et al,
I've spent basically all day trying to get a facebook like icon to work with allowing for comments (using the xfbml). It seems the problem I was having in getting it to work was your SFC core (I also had your SFC comments feature enabled). Only by disabling the core does it work.
I followed setting it up as described:
and also tried this approach:
The problem with these techniques to enable the like button using xfbml, as opposed to the iframe version which gives no comment box, is that something in your sfc-base is interferring. In Google Chrome I get no like button while your sfc-base is enabled. In IE8 I get nothing either, but many times I'll get a "out of memory" popup error (always saying line 10). Again, all of these problems instantly disappear and my like button works well enough once the sfc-base and associated items are disabled, but the base is the problem I think.
I'm happy I found the cause, but sad that I cannot use your facebook connect feature for comments, unless this is a quick fix or you have some suggestions?
