My FooGallery Galleries Are Invisible

I downloaded+installed FooGallery 1.1.8.2 yesterday and today the FooGallery page is empty ! It reports I still have the four galleries I created and populated, but this has become a tax on the delivery schedule of this website. This is happening in the parallel sandbox site I setup to tutor my client on how to maintain a website themselves. One reason for this sandbox was to teach them to tryout new things away from your production/operational site, to avoid wrecking a working website. I have since disabled a similar plugin (Simple Photo Gallery) I wanted to evaluate side-by-side with FooGallery.

I’m sure this is a conflict between plugins, but so far I haven’t found a plugin which will simply list the installed WP components (themes and plugins), so that I may post the list for someone to look at and point out what’s wrong…

Thanx for use of the eyeballs.
