Php 7.4 Rev Slider: Undefined variable: widgetName /framework/functions-wordpress.class.php

[axew3]

PHP Notice: Undefined variable: widgetName in /wp-content/plugins/revslider/includes/framework/functions-wordpress.class.php on line 259

if using an old version of revslider and new Php versions, you'll change the line 259 into this file:

Code: Select all

add_action('widgets_init', create_function('', 'return register_widget("'.$widgetName.'");'));

into this:

Code: Select all

add_action( 'widgets_init', function() { global $widgetName; return 'register_widget("'.$widgetName.'")';});

This helped a lot.
Thank you so much
