Website Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘Wppr_Public’ does not have a method ‘amp_support’

The warning message is pretty clear. You’re passing method amp_support from class Wppr_Public as callback, but this class doesn;t have such method…

So how to fix it?

You should find that class and look for this function. Maybe it’s some typo or that method changed its name or moved to another class or something like that.

PS. But there’s another problem on your site. PHP warnings should never be printed on productions sites for security reasons. You should take care of that too.
