Hi,
I have the default install of this plugin - no code changes or anything - and Vimeo videos won't embed. For instance, putting the embed code
<iframe src="//player.vimeo.com/video/102556992?title=0&byline=0&portrait=0" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
results in an error about the source not being allowed. Again, I have made no code changes, and the code for Vimeo is in the plugin providers PHP file.
Any ideas?
