Thread:Extension talk:OpenGraphMeta/Bug or User Error?

This didn't seem to output the correct format for the OG meta tags due to the addMeta function called with the BeforePageDisplay hook. Could be my fault. For example, I am getting  when it should be. Unless there's something I'm missing, addMeta will only return  formatted meta tags.

I am on MediaWiki 1.18.0, PHP 5.2.17, and MySQL 5.1.56--maybe the function addMeta has changed in the latest update? I corrected it by using the hook OutputPageBeforeHTML and the function addHeadItem to output: It seems to work. Thoughts?
