Hello.
For your template, the Go to text should be in /storefront/view/default/javascript/custom.js line 48

Hello,
I wanted to clarify that CAPTCHA and reCAPTCHA are distinct entities. The form does not return any validation errors are you sure that Processing Controller is set as default and core files are not modified?

With the upcoming upgrade to version 1.4.0, there will be significant changes to the checkout process. For existing users who are utilizing the default template and have not yet switched to Fast Checkout, please note the following:

•  Old Checkout Unavailability: After the upgrade, the old checkout system will no longer be available. We are moving towards a more streamlined and efficient checkout experience, and as such, the legacy checkout option will be retired.

•  Theme Switch to Bootstrap 5: If you are currently on the default theme, your store will automatically be upgraded to Bootstrap 5 (bs5). You should clone a default theme to an extension to stay with the old theme look.

Thank you for reaching out. The upcoming new version of AbanteCart will be 1.4.0. This version will indeed support Bootstrap 5 (BS5) as the new default theme and the new Novator template. Additionally, we have switched to fast checkout to streamline the shopping experience.

We have phased out version 1.3.5 in favor of these new advancements. As for the release date of version 1.4.0, we are working to ensure a smooth rollout and will announce the date once it is finalized.

My embedded test pages have started to behave differently. This includes the one linked to in my previous post https://forum.abantecart.com/index.php/topic,10739.0.html
Previously the Add To Cart button opened the shopping cart, now it just adds to the total, showing the cart icon.

Hello. If the product includes options, the product page will be displayed. If there are no required options, the product is added to the cart as supposed to be for "Add To Cart button"

Hello.
Enable duplication of messages to admin so you at least can see sent messages https://abantecart.atlassian.net/wiki/spaces/AD/pages/6324254/Duplicate+Contact+Enquiries

And make sure you have captcha field added as default Contact form

Ah ok thanks Basara! That puts my mind at rest.

Any idea why one customers orders don't send any notifications? Usually should get one from the shop and from PayPal but neither get sent but PayPal money arrives.

Hello. Are you referring to the email that is sent out once the order has been confirmed?
