Error copying moon image troubleshooting

[oldeflyer]

This is not a major issue for me, just curious.
I have the latest MX release running.
Trying to find where to start troubleshooting this.
In the debug file it has the line "Error copying moon image - Illegal characters in path."
A forum search did not have any hits on this error.

Is the process of these copies available to look at?
Is there a text stream that can be corrected?
I did see a moon.png file in the web subdirectory. Is it in the right place?

Thanks for any help.

Never mind.
Did some digging in the configuration file and found...
Some how there was a "?" in the path of the moon file just after the device colon.
