Widget zones definition causes an error

I installed the plugin and used it without any issues on my local host application. Once the application was deployed on azure, I re-installed the plugin and tried to configure it. I am able to define a new slide but once I try to add a widget zone I get the following error.

We're sorry, an internal error occurred.
