WP Easycart JQuery error WP 5.4.1

[mistergiu]

Hi,
I got this problem, on a page that doesn't have nothing abut the store:

"Payment is not a function"

These are the lines:
jQuery( document.getElementById( 'ec_card_number' ) ).payment( 'formatCardNumber' );
jQuery( document.getElementById( 'ec_cc_expiration' ) ).payment('formatCardExpiry');
jQuery( document.getElementById( 'ec_security_code' ) ).payment('formatCardCVC');

The error is in the first row but I tried to exclude the furst line and the errore is now in 2...

Somebdy can help me?

Thank you

Hello:

Unfortunately I"m not sure why that may be showing and we would likely need a support ticket so we can securely get login info and dive into your specific user case and server situation.

Really sorry, but I installed the plugin some days ago. This error is a blocking error for me. I'm trying some other ecommerce plugin, if I can't find something working I'll be back and pay for support.

Thank you JJones
