Webpages on Managed iPad are black

[CapU]

I configured an iPad to behave like a kiosk, locked to Safari and a webpage.
I set the Lock screen and hompage using a jpg with our logo (the image is primarily black). Now the webpage that the iPad is locked to is black, when normally it's white. What could be causing this? and how do I fix it?
Not me in the image.....

I got a call from someone from jamf today who was working on the same issue as this.

The Jamf Product Issue you are running into is PI-001340. The configurations in the Single App Mode payload that have the opposite description of what they actually do are: VoiceOver Zoom Invert Colors (I think this was your problem) Assistive Touch Speak Selection Mono Audio
