# Payment Intent ID Not Valid

 * This issue has occurred for two transactions within the past week. It was found
   after reviewing session recordings for one customer and a complaint from another(
   verified through session recording). I have Forminator form on website via short
   code.
 * User fills out form and enters payment information. When they hit submit, the
   Payment ID Not Valid error message pops up.
 * I’ve tested with live payments and could not create the error. Also, other customers
   were able to successfully checkout. I checked the Stripe Developer logs and the
   payment intent was created but there were no errors recorded.
 * This issue was potentially caused by having an older version of Forminator Pro
   we tested briefly and then deactivated a few weeks ago. We completely removed
   the Forminator Pro plugin and installed the recently updated Forminator free 
   version (we only use one-off payments which is included in the free version).
 * All evidence points to an issue within the Forminator plugin itself for these
   edge cases. Any information on how to prevent this in the future.

 * Hello [@smartbrainn12](https://wordpress.org/support/users/smartbrainn12/)
 * Thanks for reaching us. Can you please confirm that you are using the latest 
   version of Forminator? At the moment of writing this, this version is 1.55.0.
   You mentioned that you deactivated an older version of Forminator Pro, and then
   installed the latest version of the Free Forminator plugin from the WordPress
   repository, right? All the forms and configurations of the plugin should be the
   same, and there should be any issues by doing what you did. Still, I suggest 
   you to check if you also have the latest Stripe API in your Stripe Panel:
   [https://docs.stripe.com/upgrades#perform-the-upgrade](https://docs.stripe.com/upgrades#perform-the-upgrade)
 * Also, I suggest you to reconnect Forminator with Stripe. Our recommended method
   is to use the Forminator App in the Stripe panel. The instructions to do that
   can be seen here:
   [https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#connect-to-stripe](https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#connect-to-stripe)
 * Please try these two and test your form (using a Test Mode first, in the Stripe
   field options), then if everything works fine, move it to Live Mode. And let 
   us know if you experience any issues.
 * Kind regards,
   Jair.
