I ended up sticking with an old Zola binary. I'm not sure that the Zola project knew the extent of the blast radius in terms of the effect on themes when they upgraded the Tera template engine. I wouldn't mind trying a new theme. There are now 15 available (up from about 10, but down from 100+ before the upgrade).I'm liking this one: https://www.getzola.org/themes/parchment/All the current themes: https://www.getzola.org/themes/
