Upgraded to 1.5.1 failed,

After failure, I copied the backup gallery directory into the active Directory.
Now remote upload users get this error when they click on the upload button:

Gallery Remote can find no protocol implementation at the URL http://thelundgrens.us/gallery/. Check with a web browser that http://thelundgrens.us/gallery/ is a valid Gallery URL.
I then found a newer gallery remote- 1.5 and installed it.

But users get the same error:
Gallery Remote can find no protocol implementation at the URL http://thelundgrens.us/gallery/. Check with a web browser that http://thelundgrens.us/gallery/ is a valid Gallery URL.

Obviously the URL is Ok since they must login before they can use gallery remote.

Does anyone know what the protocol it is looking for, and how to turn it back on?
