Error reading from Data base
I was running Moodle 2.3.1 (using Build: 20120726).
While I was attempting to restore a course backup I was greeted with the following error
I proceeded to click on the "More information" link, and was faced with the following message:
Purge all caches
Purging these caches will delete that data from the server and force browsers to refetch data, so that you can be sure you are

appear slower for a while until the server and clients calculate new information and cache it.
Purge all caches Cancel
I Chose to purge all the caches, but the problem still persisted.
I have successfully restored other backup files in the past using the current install of Moodle.
The problematic backup file has also previously been used successfully a number of times.
I found that this same error also shows up when I select Site Registration/Administration:
Does anyone have a clue about this error and how to deal with it?
