Reply To: Installed the zip file for supermag but am having trouble editing.

Hello Beth Ann,
Thank you so much for using our theme SuperMagPro.
After installing the theme, you have to activate it. Pages and Menu never deleted, but you may activate some times.
Please follow the link here to make the site as demo.

SuperMagPro

In case of menu, Go to Appearance > Menus and set the menu on the primary location. Then menu will appear.
Hope, this will solve your problem.

Best Regards,
Acme Supports
