I added a FB Like button to my Wordpress template, and when I click Like, I receive an error, which pops up and says:There was an error liking the page. If you are the page owner, please try running your page through the linter on the Facebook devsite (https://developers.facebook.com/tools/lint/) and fixing any errors.The Lint Checker (now) gives no Error or Warnings, after I removed a duplicate og:description tag.Why is it not working? 
Facebook Like button warning, but prevents sharing
