Catchable fatal error: Object of class WC_Cart could not be converted to string

I just updated my webshop and wordpress, and every time i try to see the shop page I get this error:

Catchable fatal error: Object of class WC_Cart could not be converted to string in /var/www/eden-outcast.com/public_html/wp-includes/formatting.php on line 1109

But I can't seem to locate the problem or the solution for that matter.

In formatting.php on line 1108 - 1113 it says:

function wp_check_invalid_utf8( $string, $strip = false ) {
$string = (string) $string;
if ( 0 === strlen( $string ) ) {
    return '';
}

Although I it could be a problem with the database. Any ideas?

Solution

  • Somewhere in your active theme / any active plugins , any of it is trying to use WC_Cart object as string.

    Firstly, you can try deactivating your theme to see if that notice disappear. If that disappear than search your theme source code exactly where WC_Cart object is being used.

    If not, that do the same for plugins too, try deactivating plugins one by one to spot problematic plugins and search source code.
