I'm on the way to create my first WP multisite and like to use the Nextgen Gallery. Installation is no problem and the plugin works fine on my main site. But when I try to use the gallery in a sub site the plugin tells me that I have to update my database. So I click on 'Update database' and the plugin tells me that the update was successfully. But the message appears again and again and again.
Does anyone has an idea what I can do?
