[Plugin & Widget dev] troubleshooting with wp_unregister_sidebar_widget

Hi everybody,

I have a problem with plugin (widget) development in wordpress.

Indeed, I want to execute an action when user remove a widget from a sidebar in the admin appearance panel but I don’t have any results, I think wordpress don’t execute my function.

For more informations, I have this code in my plugin file :

add_action (‘wp_unregister_sidebar_widget’, array ($PressReviewer, ‘removeFromSidebar’));

Someone can help me, please ?

Tank you ! And have a nice day !
