Hi All,
Yes, I had these lines added to one of my wp-config.php files in a WP install too.
Thereafter I had a automatic (plugin) update overwrite some WooCommerce files, and I lost some of my modifications to the plugin. (I should have used a child theme – I know!).
So I’ve changed them too…
add_filter( ‘auto_update_plugin’, ‘__return_false’ );
add_filter( ‘auto_update_theme’, ‘__return_false’ );
All ok now.
I understand that my host (HostGator) added these filters during their automatic installation of WordPress in the first place.
Hope this helps.
