I've been using ochOpenGraph on many sites with no problem but I have one where no information seems to be fetched.
I've setup the plugin just like all my other sites but when I try to share a page on Facebook, only the page URL is displayed. Even if I scrape the pages in Facebook debugger, nothing is fetched. And strangely, if you check the page source code, all the meta tags are visible.
And if I activate the plugin's debug mode, no error shows up.
