I downloaded & installed a stand-alone version of Moodle 2.7.2+ for Windows on my computer.
I have backed up a course in the usual manner on our production site (Moodle 2.7.1) and attempted to restore it on the stand-alone installation, and it never finishes the uploading process. I see the status bar completed, but it never switches over to a URL. I even let it go over my lunch hour, so it's not a matter of time. If I click on the restore button after uploading the file via drag & drop, I get the following error:
I've also tried using the file picker instead of drag & drop, and all I get is the spinning timer after selecting the file. What can cause this to happen?
On a side note, I am able to upload plugins and install them, so it seems that only the restore functionality is broken.
