We are trying to open/save the document uploaded back in Dec 2013 under one of the requirement. Now, for some reason when we clicked on it, it's giving 500 error with message "Sorry, we had some technical problems during your last operation.". I've tried to check for the settings as provided in the other questions but nothing is helping.
Right clicked on the document to check the properties, but its showing only one 'General' tab and 'Ok' and 'cancel' button. Also, disabled Fish Eye plugin. But still getting the same error message.
Please can anyone help me with the reason, is it because of file don't exists or archived or what could be the reason for this error?
Also, what could be the other possible way to get this file (can we get it from backend database or something) ?
