Hi,
Please try go to Customize > General Options > on "Background Image for Body Boxed" > select an image and remove it later > and save it again.
Also, please upload your logo for vertical mobile nav via Customize > Logo and Header Options > Logo for Vertical Mobile Nav
After that, try it again. If the issues still appears - let's use plugin Really Simple SSL to fixed all the issues.
Best Regards,
