No Editable Content in Template Screen
Some templates that are imported from MailChimp have a different editable content html in them. We're working on a fix for that, but for now, you can very easily change it manually. Here's an example:
When you see lines like this
/* @tab Header @section Header Text */
They really need to look like this
/** * @tab Header * @section Header Text */
Remember, there's a space between the * and the @. If you do that to the sections between / and /, you'll be in good shape. Thanks!
