 * Hello,
 * When this plugin is activated it’s causing the following 401 on several resources.
   {“
   status”:”error”,”error”:”MISSING_AUTHORIZATION_HEADER”,”code”:”401″,”error_description”:”
   Authorization header not received. Either authorization header was not sent or
   it was removed by your server due to security reasons.”}
 * Our headers have:
   add_header Access-Control-Allow-Headers “Authorization”;

 * Hi [@allenjimz](https://wordpress.org/support/users/allenjimz/),
 * Thanks for reaching out.
 * The header you shared looks good, so can you please confirm if you have added
   this header after our plugin throws an error in the API response? If yes, can
   you please check if caching is enabled on your site which is not allowing the
   changes to get reflected?
 * Looking forward to your reply.
 * Thanks,
   Team miniOrange
