On my blog http://blog.udiburg.com there's a problem with the Facebook Like button plugin.
When ever someone tried to click the "like" or "recommend" it looks like it worked but when you refresh the page the click disappeared.
I've tried many different Facebook plugins and it's the same with all.
Also, when hovering on the text next to the "like" button there's a red background with question mark.
I think this has to do with the new upgrade to WordPress 3.5 as I didn't have this problem before i guess.
