You say this issue happens at ‘Aspect -> Menus’, which is apart of your theme, correct?

Sorry I meant Appearance -> Menus the WordPress default menus options.

I found out the problem after some further testing.

It was in a function I wrote in the functions.php, I used it to remove the COD payment method in certain conditions. Here’s the code:

add_filter( 'woocommerce_available_payment_gateways', 'filter_gateways', 1);
function filter_gateways( $gateways ){
        global $woocommerce;

	$amount = $woocommerce->cart->total;

	if($amount > 0)
	{
             // My Code ...
	}
        
        return $gateways;

}

I didn’t check for the $amount to be greater than 0 before my code. Sure it is some stupid error, but I still can’t find out why it only happened in the menus section and why everything was working properly without errors, checkout included 😀

If you have anything else to add that could help me understand this please feel free to respond, or I will just mark it as resolved. Thanks a lot for your time.
