First, I want to thank you very much for being a user of our WS OnePage Checkout. We hope you have found it useful for your business.

Please be informed that we have now discontinued the development of the WS OnePage Checkout Module. I apologize for any inconvenience this may have caused. The reason this module was discontinued is that how WHMCS did WHMCS 9.0.4

You can download the modules with no license code for free, or you can pay a one-time fee of $39.99 for the open-source version. 

Please open a ticket for whichever one you like. 

NOTE: YOU CAN NOT SELL THIS MODULE. IF YOU CAN MAKE ANY EDITS OR UPDATES YOU LIKE FOR YOUR COMPANY.

We would like to thank all customers, past and present, who helped to bring these inspired products to life -- including beta-testers, end-users, and forum members for their valued feedback and constructive comments.

It is never easy to make announcements of this kind.

You need to respond within 72 hours -- if not, then the deal will be closed, and the license version will not work either.

If you have any questions, please open a ticket.

Thanks again for choosing WHMCS Services. We appreciate your business!

Version: 1.0.1 Released (08/18/2026)
Maintenance

Fixed: Cart Leave Modal Improvements
- Removed the mouseleave / cursor exit trigger.
- The modal no longer appears simply because the user moves the cursor outside the browser window.
- The modal now relies on the existing click-away/navigation behaviour.

Fixed: Checkout Page Exclusion
- Added an explicit exclusion for:
cart.php?a=checkout
- The cart leave modal will not display on the checkout page.

Fixed: Cart Item Validation
- Added additional validation so the modal only displays when the WHMCS cart contains actual cart items.
- Added a second guard after the addon builds its cart summary to confirm that at least one genuine cart item exists.
- This prevents the modal from appearing for empty or incomplete cart session data.

Fixed: Product Configuration Page
- Added an explicit exclusion for:
cart.php?a=confproduct
- WHMCS temporarily stages a product in the session while the customer is still configuring it.
- Previously, this caused the addon to treat the staged product as if it had already been added to the cart.
- The modal will no longer appear while a customer is configuring a product that has not yet been committed to the cart.
- Once the product configuration is completed and the item is genuinely added to the cart, normal abandoned-cart modal behaviour resumes.

Fixed: Resulting Behavior
- Modal only displays when genuine cart items exist.
- Modal does not display while configuring a product.
- Modal does not display during checkout.
- Modal does not trigger from simple mouse movement.
- Existing click-away/navigation behavior remains in place.

Installing CleanTalk Anti-Spam is very simple. The following steps will guide you through the process:

2) Login to the admin area, go to Configuration > System Settings > ADDON MODULES
3) In the addon modules page, you will see CleanTalk Anti-Spam. Click Activate, then click Configure to see the options
4) You can access your module at 'Addons' → 'CleanTalk Anti-Spam '; you can setup what you need

If you see this on ClientTalk Portal 
My website status is "Waiting for first comment, registration or contact"!
