I have run into an issue with the Repeater plugin from Advanced Custom Fields where the drag and drop on that plugin is deactivated by the WPMU Dev Video plugin. I haven't had issue with this plugin before so I am assuming the issue is with the Video plugin?
Another person ran into it here as well:
I would really like to use both plugins as they both are premium. Thoughts? If you need some credentials to see it in action I can provide them. Thanks!
