How to remove restrictions

[Subramaniyan Namakkal Saptharishi]

I'm getting below message from the page when i am trying to set a restrictions to my page. 

You're not allowed to change these restrictions. It's either due to edit restrictions on the content, or permissions settings for this space.

Hi Subramaniyan,

Welcome to the community!

As the error message suggests, check the Space permissions on that Space (ask the admin of the Space to do this) - there's a setting for controlling whether or not users can change restrictions on pages in a Space -
