While installing the WordPress in the server I am getting below error.

Fatal error: Class 'Requests_Utility_CaseInsensitiveDictionary' not found in public_html/wp-includes/Requests/Response/Headers.php on line 13

Can any one suggest some solution?

I assume it's a clean installation so I can think of two things:

  • The upload (installation) wasn't complete
  • Some file permissions are not correct (folders: 755, files: 644)

I'd firstly try to remove all core files and re-upload everything.
