I'm working on a new theme for an existing website, and am using preview mode to preview the theme as I build it. The theme is not live. I'm previewing a signup page without a custom page template, so it should be using the pages_show_signup_wide.html template which corresponds to my new Bootstrap framework theme.
I was confused why I wasn't seeing changes made to this template, and when I inspect element, I notice that the HTML does not reflect the pages_show_signup_wide.html from a Bootstrap framework based theme. I suspect Preview is pulling in the page template from the live theme, not the theme I'm previewing. This is blocking me from working on a theme which isn't already live on my site.
This has been fixed!
