Fatal error: Class ElementorPro\Modules\ThemeBuilder\Documents\Header contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Elementor\Controls_Stack::get_name) in /home/public_html/wp-content/plugins/elementor-pro/modules/theme-builder/documents/header.php on line 8
and I am getting below error on 1.9.36 and 1.9.32 in all the places where I have tried to use Elementor widgets.
Notice: Elementor\Controls_Manager::add_control_to_stack was called incorrectly. Cannot redeclare control with same name "classic_columns"
