For some reason that I cannot find I get error when pressing "I like" on my last post. The previous posts work well, so I don't know what the problem is.
"The page failed to provide a valid list of administrators. It needs to specify the administrators using either a "fb:app_id" meta tag, or using a "fb:admins" meta tag to specify a comma-delimited list of Facebook users.".
However... the other posts work! So, how come that I have meta tags problems with only one post?
here's the link.
Any help will be welcome!
