WP Avalon Child theme

Hello

I’m trying to setup a child theme of WP Avalon in order to customize it easily.

When trying to activate the child theme I get the following error :

Warning: require_once(/home/dxxxxxf/public_html/id2s.cf/wp-content/themes/accessible-immo/lib/widgets/favorites-compare-widgets.php): failed to open stream: No such file or directory in /home/dxxxxxf/public_html/id2s.cf/wp-content/themes/wp-avalon/lib/favorites-compare/functions.php on line 23

Fatal error: require_once(): Failed opening required ‘/home/dxxxxxf/public_html/id2s.cf/wp-content/themes/accessible-immo/lib/widgets/favorites-compare-widgets.php’ (include_path=’.:/opt/cpanel/ea-php72/root/usr/share/pear’) in /home/dxxxxxf/public_html/id2s.cf/wp-content/themes/wp-avalon/lib/favorites-compare/functions.php on line 23

From there I’m stuck ??

Can you please help

Thanks in advance
