Cross-Origin Request Blocked:

When I go to the checkout page, the section for PayPal is greyed out and the loading animation goes on forever.

I looked at the console, and I see this:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://www.paypal.com/credit-presentment/log. (Reason: CORS request did not succeed). Status code: (null).

I tried adding to my htaccess but it made no difference:

<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin “*”
</IfModule>

Any ideas?
