There was a problem with WordPress 3.6 and the slimbox2. Fortunately, the latest version of slimbox2 resolves the problem. I’ve added this new version to the ZenfolioPress plugin, so update notifications should be showing up shortly.
I won’t described how I managed to lose my current WordPress database AND the backup while migrating to a new server. You would think that somebody with 24 years of IT experience would be just a little more careful. But, it happened and now I’m rebuilding. ZenfolioPress itself is fine and I’m testing a new version that adds the ability to display four different sizes of square thumbnails.
I’ll get the user instructions reposted first and then I’ll clean up the rest of the site.
