 * Hello, I’m trying to set up a shipping to a city (Praha). On checkout page it
   says:
 * Warning: preg_grep() expects parameter 2 to be array, bool given in /data/web/
   virtuals/230247/virtual/www/domains/breakfaststory.cz/wp-content/plugins/cities-
   shipping-zones-for-woocommerce/cities-shipping-zones-for-woocommerce.php on line
   210
 * Anyway I think everythink works, but the error message is distracting. Do you
   know how to fix this, please?
 * Thank you!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcheckout-error-23%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi Krystof, Thanks for reporting!
    Please update to the latest version of the
