I upgraded 2.2 -> 2.3 and the site is up and running.
I enabled Enabled user albums in the user settings and each time I logged in, an error occurred and I could not continue (see attached). I was able to reconnect to the gallery entry page by clearing browser cookies and cache. I was unable to login to disable the user albums, but finally found the entry in the galleryserverpro.config file and disabled it there.
Also, each time I tried to login, a new album was created for the same user (even though I was only able to see the error warning notice page.
