Sorry – that’s what I get for posting after hours of trying to figure it out. Blurry eyes.
When I went to the page the only setting that had a value was the Container width. I erased that, saved, then used the slider to bring the original value back and all is right. I assume there was some sort of corruption introduced when an update was applied.
Thanks for the help, a donation is coming your way… or maybe I’ll buy the mobile version!
