Troubles with adding video provider to Video Embed Field module I have installed Video Embed Field module, youtube links works good. Next I have installed Video Embed Wistia, and can't set valid Wistia's links. The error is  


  Could not find a video provider to handle the given URL.


Video embed field and Video Embed Wistia modules are on in admin/modules

What I have missed? Why it doesn't work?
I've found solution, it's simple.

You need to go in the field settings of this field and find a checkboxes   with all video providers. Mark Wistia or any new provider here and it will work.
