it seems that not all parts was really succesful in your upgrade process.
What I notice:
normally the old folder _uncategorised_files
is deleted during the upgrade process. Instead, a new category named Uncategorised
is created (along with a new folder with the same name). If there are unauthorized downloads in the old version, they are then moved to the new folder. After the upgrade process is completed, the user is notified of this operation (pic 1). Should also be noted in the installation log.
But I see in your pic that the Uncategorized
folder does not exist! Instead exist the old folder _uncategorised_files
Please check whether you have a Category like Uncategorised
Please check also the installation log file (pic 2) and send it me via PM. You can find it in the administrator/logs
Okay I see now that you have restored a backup. So this information not more exist. sorry.
But I will try to find out what could be the reason for your 'uncategorised folder' problem.
Do the folder names in the jdownloads directory have to be without spaces?
