Update: This issue has now been fixed by PayPal and you don’t need to do anything. If you suffered lost revenue today, direct your questions at PayPal.
PayPal has been intermittently broken with WooCommerce for a little while now, but normally trying to check out again would fix it, or switching to Firefox.
This is obviously not good for your revenue if you’re using PayPal with WooCommerce.
10 hours ago, things got worse. It seems PayPal has altered how they are handling the ‘cancel url’ and they are outright rejecting any URLs which don’t conform.
Here are the three different error messages your users will be intermittently seeing:
A fix is yet to be released by WooCommerce and/or PayPal but in the meantime, here are a couple of ways to fix it:
Table of Contents
Fix by adding filter to functions.php
If you’re comfortable editing code, stick this in your functions.php file until WooCommerce confirm the problem is fixed – then you can remove it.
add_filter( 'woocommerce_paypal_args', 'woo_override_cancel_url', 10, 2 );
function woo_override_cancel_url( $args, $order ) {
$args['cancel_return'] = urlencode( $order->get_cancel_order_url_raw() );
return $args;
}
If you don’t want to edit code, I made a plugin for you. Original title I know – it’s literally just the code above inside the plugin.

Notes
This fix may break the ability for users to click ‘cancel’ and return correctly to your store. That’s not as bad as not being able to transact.
