Difficulty Configuring Payment Gateways

[modismos]

Hello everyone,

I'm new to PrestaShop and have been setting up my online store over the past few days. I've encountered an issue with configuring payment gateways. I've tried integrating both PayPal and Stripe, but I'm running into some problems.

Here are the steps I've followed so far:

1. Installed the official PayPal and Stripe modules from the PrestaShop Addons Marketplace.
2. Configured the modules with the necessary API keys and credentials provided by PayPal and Stripe.
3. Enabled the payment methods in the Payment Preferences section.

Despite doing all this, customers are either unable to select a payment method during checkout or encounter errors when attempting to process a payment. Specifically:

• For PayPal, customers see an error message stating "We're sorry, things don't appear to be working right now. Please try again later."
• For Stripe, the payment page simply refreshes without processing the payment, and no error message is displayed.

I've double-checked my API keys and module settings, and everything seems to be correct. My PrestaShop version is up to date, and I've cleared the cache multiple times, but the issue persists.

Has anyone else faced similar problems? Are there any additional settings or configurations I might be missing?

Any advice or guidance on how to resolve this issue would be greatly appreciated!

Thanks!
