Remove ‘Add slideshow’ button from all WYSIWYG editors

Found it, but would still be nice to have a setting for it … ??

Snippet or mu-plugin:
add_filter( 'metaslider_capability', '__return_false');

Actually that doesn’t work as expected, as it also removes the menu items etc.

And from what I can tell the code doesn’t add possibilities for removing it with a simple snippet, but please tell me how to do it if I’m wrong …

Hi,

Please add the following code below to your functions.php to hide the Add Slideshow button from the classic editor.

add_action( 'init', 'remove_filters' );
function remove_filters(){
    global $wp_filter;
   
    foreach($wp_filter['media_buttons']->callbacks[10] as $filter_callback => $value) {
    	if(strpos($filter_callback, 'insert_metaslider_button') !== false) {
    		unset($wp_filter['media_buttons']->callbacks[10][$filter_callback]);	
    	}
    }
}

Works nicely, thanks. ??
