I am trying to activate the theme but I get the following error “A template file called index.hbs and post.hbs must be present”
The error indicates that you are uploading the whole file downloaded from Themeforest. After downloading the file – unzip it – inside you will find proper theme files e.g. “themename-x.x.x.zip” and documentation.
I get an error about missing theme files when visiting sign-in and sign-up pages e.g. “Missing template members/signin.hbs for route /signin/”
Your routes.yaml file indicates routes for sign-in and sign-up pages that are not used by this theme. Upload the default file routes.yaml or remove the lines pointing to /signin/ and /signup/ pages.
I can’t install the theme, because it says that there is a style.css problem
This is a Ghost theme and it requires a Ghost installation to work properly. The error message indicates that you are trying to install it to WordPress blog.
