Image upload runtime error.

I can't upload any images to my unpublished geopage. I tried multiple browsers. I always get this error message:

Server Error in '/' Application.

Runtime Error

Description: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.

For anyone having this issue in the future.

 

I converted the file from png -> jpg and it fixed.
