Fatal Error on Product 404 page (Prestashop)

Hi @NicolasK and welcome to the Community!

As an initial step, I would suggest to try the following:

• Delete the Cookies & Cache of your browser
• Try viewing with a different browser
• Restart your computer
• Erase/delete the current download on your PC for the "Klaviyo module"
  1. In Prestashop, their add-ons or 3rd party platforms for integrations like Klaviyo are called "Modules". -> Klaviyo Module
• Try a hard refresh: https://www.getfilecloud.com/blog/2015/03/tech-tip-how-to-do-hard-refresh-in-browsers/
• Then...
    1. Visit out help article -> How to Integrate with PrestaShop
    2. Reinstall the "Klaviyo module" download
    3. Proceed with the connecting of both platforms

If that doesn’t alleviate the issue, it may also be helpful to modify your server’s .htaccess file according to this thread:

I hope this helps, and thanks for using the Community!

Hi @Brian Turcotte ,

Thank you for your answer.

I tried on differents browsers, differents computers the problem is allways the same.

The module reinstallation didn’t change anything.

I update too.

We don’t have autorization problem with htaccess.

The communication between klaviyo module and klaviyo website works.

I tried on other website using prestashop and Klaviyo, some of them have the same problem.

This is not an isolated problem.

You can try.

Go on a Prestashop website, change the “product id” on the url.

If the “id” isn’t active, with Klaviyo the website will return a “fatal error” instead a 404.

Hi @NicolasK!

Seeing as the expected troubleshooting tips were unsuccessful, I am going to reach out to Engineering to determine if this is a wider-known issue. I will update the thread as soon as I can gather more information.

Thanks again for being a Community member!

Hi @NicolasK!

My apologies for the delay in response here - may I ask what version of Prestashop you are integrating with?

Also, I see that you filed a Support ticket and received a response - it may be helpful to follow up there for more account-personalized troubleshooting as they have more access.

Thanks,

Brian

Hi,

Someone is looking at this task?

Thank you,

Best regards,

Nicolas.

Hi @NicolasK!

I spoke to Engineering about this and they recommend that the best course of action would be to follow up on the existing Support ticket or create a new one, as Support will be able to provide more account-specific troubleshooting.

If they recommend following steps that already were covered here and didn’t work, feel free to let them know and I can assure you that they will offer alternative troubleshooting steps!

Best,

Brian
