I updated AbanteCart to 1.4.2 the update critically failed. After that the embeded code wouldn't work no matter what I tried, even rolling back to a fresh install of 1.4.1. When you go to the admin control panel, then select products, then select a product, then get embed code, the preview wouldn't appear. Furthermore if you went to a page with embeds in it and opened dev mode you would get an error.
In Chrome it's:
Cross-Origin Read Blocking (CORB) blocked a cross-origin response.
In Firefox it's:
The resource from was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff)

After working on this error for more than I day I figured out the problem. The webserver wouldn't serve index.php as the default index file, so any call to javascript would return 404, which was the wrong file type since it was expecting javascript, and it would get blocked.

The solution is go to the .htaccess file in the root folder of your AbanteCart installation and add this line:
DirectoryIndex index.php

You're right — Stripe does support multiple payment methods like Apple Pay, Google Pay, Klarna, and more. However, AbanteCart's default Stripe extension is often limited to basic credit card payments only, unless it's extended or modified.

Here’s how you can potentially resolve this:

✅ Steps to Enable Other Stripe Payment Methods in AbanteCart:
1. Check for Extension Updates
Go to your AbanteCart admin panel → Extensions → Payments.

Locate Stripe and check for updates.

Sometimes, new versions add support for more payment methods.

2. Use a Third-Party Stripe Integration
The default Stripe plugin might not support all payment methods.

Check AbanteCart Marketplace or GitHub for enhanced Stripe extensions that support Apple Pay, Klarna, etc.

Some paid modules offer advanced Stripe features.

3. Use Stripe’s PaymentElement or Checkout Integration
You can customize the integration by using Stripe’s Payment Element or Stripe Checkout in your custom code.

This allows:

Apple Pay / Google Pay

Klarna

ACH

Afterpay/Clearpay

iDEAL, SEPA, and more

➡️ This requires some coding knowledge or help from a developer.

4. Enable Payment Methods in Stripe Dashboard
You mentioned already enabling them — good!

Just ensure you’ve enabled the methods for the correct region in your Stripe Dashboard.
