While uploading the theme to Shopify I get this error: “zip does not contain a valid theme: 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 4 items – Readme.txt, Changelog.txt, Documentation folder and Packages folder. The file you have to upload to Shopify is a .zip file in Packages folder (rt-material.zip).
