I have a multisite install set up and I am using the Headway Theme (which I believe you folks are familiar with).
That being said, I had an issue come up which perplexed even the experts but after some time I was able to solve but it has created another issue.
Here is the problem
When using the Headway and the domain mapping plugin, I have to change the site address from http://www.examplewebsite.simplpress.com to http://www.examplewebsite.com in the network admin settings in order for the Visual Editor of the Headway theme to load once I enable Domain Mapping.
However, this has created another issue in that the Video tutorials will not load.
I realize that perhaps I am placing this under the wrong support category but its all so complex and is related to domain mapping.
If someone could let me know how to resolve this issue I would greatly appreciate it.
