Reply To: Error message when adding the shortcode

Can you please do a little test for me (since this is your test site).

Open the following file of the plugin:

stripe-payments/public/includes/class-shortcode-asp.php

Go to line number 349. The following line:

$item_price = $price * 100;

Change it to the following and save the file:

$item_price = floatval($price) * 100;

Does it make a difference after that?
