Can’t edit login/signup page code shows instead

Hello,

Thank you for reaching out to us.

The behavior shown in your video is expected and functions as intended. Allow us to explain:

By default, the account page contains only the WooCommerce shortcode, which displays either the user dashboard or the login form on the frontend. This functionality is not theme-dependent but rather comes from the WooCommerce plugin itself https://woocommerce.com/document/woocommerce-shortcodes/page-shortcodes/#my-account

Our theme introduces additional settings for this page, including the display of products that you see. If you wish to disable this feature, you can do so by navigating to:
WooCommerce > Settings > Account > XStore “My Account” Page Settings > Change Account Page Type
Here is a reference screenshot: https://prnt.sc/1SOvb7jFgG-s

Additionally, Elementor can indeed be used to customize the account page. You can follow the instructions provided in our documentation here:
https://www.8theme.com/documentation/xstore/xstore-builders/xstore-my-account-page-builder-with-elementor/

If your concern is related to the color of the “Add to Cart” button, you can modify it via:
Theme Options > Styling > Button Settings.

To adjust the border radius of product images, you may apply custom CSS code.

We hope this information is helpful. Please feel free to reach out if you need any further assistance.

Warm Regards,
The 8Theme Team
