With the recent release of Jekyll, it gets the built-in ability to support themes, since we’ve already added theme support in 2015, the original config variables theme would be conflicted with the built-in one.
To solve this issue, I’ve renamed our theme option to amsf_theme. And here’s what you need to do to resolve compatibility issues after upgrading to latest Almace Scaffolding:
- Rename your original 
themeoption in_amsf.ymltoamsf_theme. - Add 
amsf_theme_urlwith your theme Git URL. - Replace all 
site.themewithsite.amsf_themein your page templates.
