I am working with the Mosaico extension in WordPress with Civi 4.7.20.
If I go to build a template the template builder loads OK. I get several errors when working on the template.
When a template loads the image placement areas do not show an image and if I upload an image I get an internal server error.
When I try to save an template I get an unexpected error, please contact us. This only occurs on the versafix-1 template the tedc15 template saves OK.
Not sure if it is a bug or configuration issue.
