I am unable to access my gallery, all I get is this:
"The script detect that you upgrade from a older version. Your database tables for NextGEN Gallery is out-of-date, and must be upgraded before you can continue. If you would like to downgrade later, please make first a complete backup of your database and the images.
The upgrade process may take a while, so please be patient.
Start upgrade now..."
When I press Start Upgrade now, nothing happens. What do I do?
