Receiving this error after upgrading. I'm able to upload the old widgets back into the /widgets/ folder and connect them up again to clear the error, but I'd like to know what I'm missing that would be causing the issue.
Fatal error: Class 'CI_WC_Widget_Best_Sellers' not found in /home/.../public_html/wp-includes/widgets.php on line 324
If I re-add each old widget one-by-one, the error pops up for the next old widget.
1. I do not have any WooCommerce widgets active in the theme
2. The theme is WooTheme's Intrigue theme.
