OK, please take a look: https://www.flyinggoatcellars.com/about/the-vineyards
These images have captions. Do they work correctly, um – no.
This page uses captions also: https://www.flyinggoatcellars.com/about/norman-kate
And these work correctly! Same site, same css, and both of these pages worked correctly prior to installing Membership. Maybe it’s a coincidence, but what the heck? Any suggestions?
