I am unable to backup my course. Clicking Backup always results in a Server Error:
500 - Internal server error.I have debugging turned on at the Developer level, but I am not getting any errors logged to help me track down the cause.
I have checked that all of the plugins (both default and additional) are up to date (clicking the Check for Updates button doesn't identify any plugins that need to be updated).
I have not made any changes to the core and changes to my existing plugins is strictly limited to layout and style changes; namely commenting out items on the display I would rather my users didn't see that I couldn't remove through settings within the UI.
I'm totally stuck and need to backup my base course so that I can duplicate it several times with minor changes depending on the intended audience as opposed to manually copying every change and update I make to the course five times.
What else can I provide to get this issue resolved?
