different theme for different pages

We have set of pages which uses custom theme that we created. However, the pages does not work if we login using other profiles.
Please help.

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.
