I upgraded my test site to the new version, and everything with the theme seems to work properly in my test instance. I haven't updated my production site yet because of an unrelated matter with a plugin, but as far as the theme goes, it's just fine.

Thanks, what plugin on the prod site?

It's "Copyrights" and "OpenStreetMap".  They both have warning mark that indicates that the plugins may not be compatible with the current Piwigo version, though they both work just fine on the test site.  The way I see it, there is no hurry to update, so I'm willing to wait a little bit for the authors to push out compatibility updates.  So it's more of an abundance of caution for me than anything else.  I probably could do the update and be just fine, but I'm waiting a little while.

Yep, that got it. They now have updates, and I successfully updated to the new version.
