Issues with Plateau theme in Web AppBuilder

[LucasRosen]

Hello,

I am creating a web application using the plateau theme. Yesterday, the theme would not load and I received an error. I tested it with other themes and some worked and some didn't. Today it works again. Is there a reason this is happening?

Cheers.

Luke

Have you opened the console/dev tools to see any error messages?

Here is the error that I get:

Try creating a new empty application and choose that theme. This error might suggest you had some previous widgets defined that are unable to be moved to the new theme
