I'm just getting started with Prestashop, I have done a local install and duplicated the default-bootstrap theme, renaming it *mynewtheme*.
I go to Preferences > Themes and there no sign of mynewtheme?
I also tried 'Add new theme' and 'Import from my computer'. I created a zip of mynewtheme, selected the file and hit save. There was an error: Bad configuration file
What gives?
