Is there a way of editing or changing the fields on the billing details/order form? * All hte best * Normski * [Ragnar Karlsson](https://wordpress.org/support/users/ragnarkarlsson/) * (@ragnarkarlsson) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133277) * My suspicion is that there is an underlying issue with this though, my test site doesn’t need this fix on 1.10.5 whilst the live site does. * Jigoshop team – can you replicate? * I use the Checkout Fields Manager currently: [https://www.jigoshop.com/product/checkout-fields-manager/](https://www.jigoshop.com/product/checkout-fields-manager/) * Plugin Author [Jigoshop Support – Paul](https://wordpress.org/support/users/paulpreston/) * (@paulpreston) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133278) * we are looking into it now… * [Ragnar Karlsson](https://wordpress.org/support/users/ragnarkarlsson/) * (@ragnarkarlsson) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133279) * Thanks Paul much appreciated. * [megawebmaster](https://wordpress.org/support/users/megawebmaster/) * (@megawebmaster) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133280) * Can I get the postcode you are having problems with? I tested it on a few things and moreover the code for validationg was not changed. The only thing is adding frontend validation in JavaScript (to speed up validation). * [Ragnar Karlsson](https://wordpress.org/support/users/ragnarkarlsson/) * (@ragnarkarlsson) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133281) * I tried using PL9 7YB (pinched direct from Royal Mail website) * Please note that the javascript validation doesn’t appear to be the issue I’m facing but rather jigoshop_validation.class.php * I can send system info to [support@jigoshop.com](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/support@jigoshop.com?output_format=md) if that is of help? * [megawebmaster](https://wordpress.org/support/users/megawebmaster/) * (@megawebmaster) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133284) * OK, the problem exists – will be fixed in 1.10.6 * [Ragnar Karlsson](https://wordpress.org/support/users/ragnarkarlsson/) * (@ragnarkarlsson) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133285) * Great, thanks folks * Thread Starter [normski](https://wordpress.org/support/users/normski/) * (@normski) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133287) * Thank you Ragnar and Amadeusz. * [andytoop](https://wordpress.org/support/users/andytoop/) * (@andytoop) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133325) * Great that it will be fixed, but what about all the folks that can’t order on my shop at the moment? when will 1.10.6 be available? * where do I find: jigoshop/classes/jigoshop_validation.class.php as posted up on Ragnar’s post * Andy * [andytoop](https://wordpress.org/support/users/andytoop/) * (@andytoop) * [11 years, 10 months ago](https://wordpress.org/support/topic/postcode-billing-is-not-a-valid-postcodezip/#post-5133326) * found it ta.
