Here is the error I get when I try vimeo.
✖ Error: Error retrieving video information from the URL http://vimeo.com/api/oembed.xml?url=http%3A//vimeo.com/64995776 using wp_remote_get()
If opening that URL in your web browser returns anything else than an error page, the problem may be related to your web server and might be something your host administrator can solve.
Details: Couldn’t resolve host ‘vimeo.com’
Yes, I am logged in when I am viewing the front end, but still no bar is showing 🙁
