remove_action not working, even after changing priority [duplicate]

Question

So one of the functions in my theme is:

public function job_manager_job_filters_distance() {
   //Show some HTML
}

And somewhere else in the document lies:

add_action( 'job_manager_job_filters_search_jobs_end', array( $this, 'job_manager_job_filters_distance' ), 0 );

I want to disable this function.

So naturally I went to my child theme's functions.php and added remove_action:

remove_action( 'job_manager_job_filters_search_jobs_end', 'job_manager_job_filters_distance' );

It didn't work. Then I tried different priorities for the removal:

remove_action( 'job_manager_job_filters_search_jobs_end', 'job_manager_job_filters_distance', 20 );

Still no go. Then I tried to wrap it in a function that triggers after theme load:

function remove_listify_junk() {
    remove_action( 'job_manager_job_filters_search_jobs_end', 'job_manager_job_filters_distance' );
}
add_action( 'after_setup_theme', 'remove_listify_junk', 999 );

And the function is still doing it's thing =[...

What am I missing here?

You are trying to unhook a PHP function as opposed to a (class) instance method - see here:

array( $this, 'job_manager_job_filters_distance' )

...that's the actual callback registered to the hook. To unhook you need the same (a reference to the instance).

If you are trying to unhook from within the class, it's as easy as using the above. Otherwise you need a reference to the instance - look for something like the following in your code:

$my_class = new Name_Of_Class;

...then you'd run:

remove_action( 'job_manager_job_filters_search_jobs_end', array( $my_class, 'job_manager_job_filters_distance' ) , 0 );
