 * Hi,
 * Since one of the recent updates I receive the following error message during 
   my WooCommerce Checkout Page:
 * Notice: Trying to access array offset on value of type bool in /www/htdocs/w018a855/
   alphaville-my-passion.com/wp-content/plugins/seo-by-rank-math/includes/replace-
   variables/class-post-variables.php on line 537
 * Besides of this error my payment methods (PayPal and Stripe) do not get loaded
   anymore (so nobody can pay).
 * I have built my checkout page with the Plugin Cart Flows (Pro-Version).
 * After deactivating Rank Math Plugin the error message is away and checkout works
   normal again, also payment is again possible.
 * What can I do?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-error-on-checkout-page%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
