Browser cache problem

[esgriguita]

Good morning,

I have a problem that sometimes occurs both to me and to clients who enter the website and go through the process of making a purchase.

For some reason that I don't know, if customers reach the checkout page and at that moment do not complete the purchase and close the tab in the browser or go back or reload, when they return to the checkout page and click to finish the purchase, the page remains blocked and instead of going to the payment gateway, it stays in a loop and loads the checkout page again or when trying to enter the checkout, it redirects them to the main page.

I have verified that clearing the browser cache solves this, but many customers abandon the page for this reason.

Any ideas why this happens and how to fix it permanently without having to clear the browser cache?

Thanks in advance.

Hi,

• If you're using any server-side caching mechanisms such as Varnish or Redis, make sure that they are configured correctly. Sometimes, these caching layers can interfere with dynamic content generation, causing issues similar to what you're experiencing.
• Check PrestaShop's caching settings and consider adjusting them to ensure that checkout pages are not cached or are cached with appropriate expiration times.
• Use browser developer tools to check for any JavaScript errors that might be occurring when customers try to complete their purchase.

Thanks!
