I was able to edit the changes in the xml and rezip it as a .mbz. I switched around the command line a bit. I used:
zip -r somebackupfile.mbz *
The one you gave me was only zipping the first file in my test folder.
I tried using this file to restore, but still no luck. But I'm wondering if it worked correctly, because whenever I look at the folder created in the moodledata->backup, it only shows the first file in that test folder (but if I unzip the file on my computer, it shows all the files).
But if this isn't the problem, then I will follow your advice from the next post, which is to dive into the error logs.
So first off, I turned on debugging, but I have no idea where to check the logs once I turned it on. Could you tell me where they would be?
