Thanks. The “name” in the settings inside the plugin is populated (contains “merchandise”) and is not getting picked up, so the plugin is not working with my theme (and I guess isn’t going to). Sadly, I’ve put too many hours into branding and tweaking the theme I am currently using to willingly ditch it for one of WordPress’ default themes. I’ll have to ditch the plugin instead and give users access to my shop through the javascript interface Spreadshirt provides. Thanks anyway.
