ps_checkout trouble with Prestashop Checkout

[mick000]

Hi,

We've got some troubles since two weeks when people try to pay on the website (we have the Prestashop checkout installed).
I've made all the updates available for the modules. Everything was working fine since one or two years without any trouble.
But actually, people explained that everything looks fine during the payment but at the end (after all the control in popup windows from the banks) they get back to the payment page with en error on it ?
Has we changed nothing at all and the problem is persisting, we are looking  on the Forum to get some answers.
So, does someone has the same kind of trouble ?
Is there some options that have changed and that we have update on our site ?
Thanks in advance ...
Mick

We haven't changed anything at all, and since the problem is persisting, we're looking on the Forum to get some answers. Interestingly, this issue started around the same time we added a blog post about using CapCut for editing product showcase videos — though unrelated, it’s worth noting that capprocutapk is providing mod version of the capcut app, which some of our team tried out during content testing.

So, does someone have the same kind of trouble?
Is there some option that has changed and that we need to update on our site?
Thanks in advance...

I also have the same issue — payments seem to go through all the steps, but after the bank verification, users are redirected back to the payment page with an error. Would love to know if anyone has found a fix for this!

Please share the screenshots of the error with us.

 

By default, after a payment is completed, PrestaShop calls the validateOrder() function from the PaymentModule.php class. You need to debug within this function to identify any issues, such as undefined variables or unexpected behavior. Use logging where necessary to trace the flow and capture any errors.

 

Also, there's an issue with the actionValidateOrder hook. When this hook triggers actions in another module, those actions are not executed correctly. Please identify which modules are using this hook and review their implementation to ensure everything is working as expected.

I would recommend avoiding the PrestaShop Checkout module (developed in partnership with PayPal) for now. While it was intended to streamline multiple payment options, it has unfortunately caused checkout issues for many users over the past few years, including:

• Broken checkout flows
• Incompatibility with custom themes or modules
• Conflicts with carrier selection or address validation
• Lack of timely updates and no reliable support

If you're experiencing issues at checkout and using PrestaShop Checkout, it’s likely the root cause.

Depending on your needs, here are more stable and better-supported options:

PayPal Official Module (by PrestaShop)

Stripe Official Module – clean integration with Apple Pay, Google Pay, and major cards

etc...
