That screenshot is too small to read the text. Your hosting company is guessing. The API is up to date.

What kind of web hosting do you have? I think there is a technical issue here.. most likely something being blocked, rejected or not available.

The paypal_commerce folder needs to reside in the modules/plugins folder.

Strange. I've never experienced this. Maybe clear cookies and try again later. Sorry you are having problems.

Disconnect the PayPal Commerce extension and then connect again. Can you try that? Make sure you complete all onboarding steps and do not close the popup window with the X in the top corner. The last blue button return to store is critical.

What about in the request log in the admin control panel?

What payment gateway are you using? Are there and browser errors reported in the browser console?

It's probably a server side firewall blocking curl requests. This needs much deeper investigation.

In what way doesn't the payment page work? Do the other parts work such as the yellow express checkout button? I know that the card part can take longer to become active as PayPal as to perform risk assessment.

Did you click the las big blue button in the middle? Do not click the X at the top right of the page.

Does it look like this?

The screenshot suggest that vital PayPal components haven't ben loaded. Please do two things; 1. Make sure the extension is at the latest version 2. Make sure you have a secure SSL connection. You must be logged into your store admin control panel over SSL.

You need to login to PayPay and set phone number to be required. Log in to your PayPal account at paypal.com. Click the gear icon and select Account Settings. Click Website payments. Beside Website preferences, click Update. In Contact telephone number, choose an option for Contact telephone: On (Required Field) - requires that your customer enter their phone number when checking out.

I believe the Adyen integration will support Klarna. We do however have a very good PayPal Commerce integration which has Pay in 3. It's essentially the same offering as Klarna and Clearpay.

Have you gone to the /setup folder to upgrade to the latest version?
