Hi All,

Can someone pls help me in resolving the validation error I am getting while previewing the course. This error message says "Error generating preview, please contact your Administrator". 

I am new to the tool and after creating my first course I got this message which is stopping me to move ahead. I am not sure what could be the reason of this error. I tried every other possible ways. 

Please respond if anyone finds any clue to resolve the issue. Screenshot attached.
