Cannot load any shipping extension on Abantecart (localhost - XAMPP)

[yiedpozi]

Describe the bug

After performing a fresh installation of Abantecart version 1.3.3, I tried to add a product on the storefront. However, upon being redirected to the cart page, I received the following error message: undefined

Upon checking the Network tab in my Chrome browser, got 400 HTTP error on index.php?rt=r/checkout/cart/change_zone_get_shipping_methods. The response is as follows:

{
    "error_title": "Application Error!",
    "error_text": "Please check error log for more information",
    "error_code": 400
}

This is the error log message from the system/logs/error.txt file.

2023-07-07 9:29:12 - load error:  AbanteCart core v.1.3.3 Error: Could not load model extension/default_flat_rate_shipping

I also tried to disable the flat rate shipping and use another shipping method, but I encountered the same error.

Steps to Reproduce

1. Install Abantecart version 1.3.3 on XAMPP.
2. Add any product, then navigate to the cart page.
3. You will see an error message popping up on your cart page as per above screenshot.

Expected Behaviour

After adding a product to the cart, we should be able to see the item and select a shipping method on the cart page.

Environment

• XAMPP: 8.0.7
• PHP: 8.0.7

Hello. Make sure the URL you visit and Store URl are same in your settings https://abantecart.atlassian.net/wiki/spaces/AD/pages/5832828/Store+URLs+SSL

[yiedpozi]

Store URL set in the system settings:

Cart page that I visited: http://localhost/abantecart/index.php?rt=checkout/cart

[BasaraABC]

Please try to set both the Store url and Secure url and enable HTTPS for both. For localhost accept browser warning to visit site.

Still returns same error message on https://localhost/abantecart/index.php?rt=checkout/cart after updating both Store URL and Secure URL and enable HTTPS for both settings. Also tried on incognito, same results.

_Could not load model extension/default_flat_rateshipping @yiedpozi is this file presents on hard drive? i mean public_html/extensions/default_flat_rate_shipping/storefront/model/extension/default_flat_rate_shipping.php

[yiedpozi]

Yup, the file exists and accessible.

[BasaraABC]

@yiedpozi the file permissions can be incorrect and your local server cannot access it

[yiedpozi]

Nope, file permissions is okay.

The issue can be OS-related (if you have Windows) you can try to use a docker for localhost https://hub.docker.com/r/abantecart/abantecart https://abantecart.atlassian.net/wiki/spaces/AD/pages/1118339077/Docker+Installation

Issue solved after using Docker on my OS (Windows), as recommended by @BasaraABC. Thanks ya.
