different theme for different pages

Hi Neena~

A few questions for you: 

  • Did you set the custom theme as your organization default theme in Theme Assignments? 
  • Do you have profile and/or user-level overrides of the themes? 
  • Are the same set of pages deployed to all profiles or were different profiles assigned different pages in the page assignments?  

Please check out the following tutorials: 
Does any of the above fix the problem? If not, please let us know. 

Thanks!
Karen
