While uploading the theme to Shopify I get this error: “Theme does not contain all required files: missing template “layout/theme.liquid””
This happens when you are trying to upload the incorrect .zip to Shopify. 99% of the time this happens when the folder that was downloaded from Themeforest was NOT unzipped beforehand.
Within the folder there are 3 items – Readme.txt, Documentation folder and a .zip file. The file you have to upload to Shopify is Callisto.zip.
