** **This question is outdated!** **

I use the bellow function to disable a plugin update. It works, because I use an old version of this plugin and it does not show me that a newer version exists, but, however, I get a warning on line 2: *Attempt to modify property of non-object*. How to fix this?

    function my_filter_plugin_updates( $value ) {
       unset( $value->response['duplicator/duplicator.php'] ); //Duplicator
       return $value;
    }
    
    add_filter( 'site_transient_update_plugins', 'my_filter_plugin_updates' );
<br />
**UPDATE**

I am not a PHP coder, so I do not know if what I did is correct, but this works - no errors, no warnings, no plugin update:

    // Disable plugin update
    function my_filter_plugin_updates() {
       $value = new StdClass;
       unset( $value->response['duplicator/duplicator.php'] ); //Duplicator
       return $value;
    }
    
    add_filter( 'site_transient_update_plugins', 'my_filter_plugin_updates' );
