Hi,
Is anyone else experiencing problems with the PayPal module?
It was working fine on my site until recently and then suddenly stopped working.
Now, when I activate Express Checkout I get a Server Error 500 when clicking on product pages on my site http://s-uk.co
Also, login in with PayPal no longer works.
The following error message is returned:
Relying Party Validation error: redirect_uri provided in the request does not match with the registered redirect_uri. Please check the request.
The folders have 755 permissions and the files are all 644.
I have entered my PayPal API Credentials, the LIVE Client ID and Secret, and also the return URL as per the documentation.
I am using Prestashop v1.6.0.9 and PayPal v3.8.4
Any help would be greatly appreciated
