Recently (last couple of weeks) downloaded the Gallery Appliance as a VM machine. Worked well and have uploaded many photographs. On the point of going live when the site can suddenly no longer be accessed. "Error" is the only message displayed when trying to access main.php in a web browser.
Haven't made any changes to cause this. Linux VM machine boots ok, no apparent error messages. Possible that mysql is not loading as cannot stop-start this server.
