Same error, it stops people from adding coupons on the cart page.

The order of the arguments needs to be swapped. Change /includes/view/frontend/general.php:75 from

if (method_exists('is_empty', WC()->cart) && WC()->cart->is_empty()) {

to

if ( method_exists( WC()->cart, 'is_empty' ) && WC()->cart->is_empty() ) {

as per https://www.php.net/manual/en/function.method-exists.php

Hello there, I have just applied the change proposed by @brianhenryie and it worked.

You need to go to plugins editor, select the direct chekcout plugin and edit the line 75 in the named directory. (/includes/view/frontend/general.php:75) or the one that the warning is telling you to solve.

Thank you @brianhenryie

Hi
sorry for the delay
could you test version 2.4.2 and confirm if it is solved or not?

Hello,
