Hi,

I'm trying to get paypal to work on our new shop with its new SSL and when I press the Paypal Express logo I keep getting

"PayPal Payment Pro error: Security error
Security header is not valid"

Can anyone please tell me what I've not done please??

Using PHP 6.9.4


Trace

Would this help?
[url]http://paypal.payment.pro.error.security.error.security.header.is.not.valid.errorwiki.org/[/url]

Also make sure that in the main ECT admin that BOTH urls; HTTPS Store URL: & Store URL: are showing as https

In your htaccess file make sure that your SSL headers are set correctly

The following three lines may vary according to your host. I'd check with your host just in case they differ
[blue]RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301][/blue]

#SetsTheStrictTransportSecurityHeaders
[blue]Header set Strict-Transport-Security "max-age=31536000" env=HTTPS[/blue]

Thanks but no that didn't fix it

Has it been working, or are you adding Paypal services?

Paypal express and Paypal pro are two different services.
You can have both, but if you click the paypal express button and get a message regarding paypal payment pro error, that doesn't seem right.

If you want to use Paypal payments pro, (Paypal direct in your admin) where customers pay on your site, then use these instructions - https://www.ecommercetemplates.com/phphelp/ecommplus/paypal-pro.asp

Thank you - sorted and its working at last.

I went through and double checked all settings and I'd made a silly mistake of selecting API Signature and not certificate.

Thought I'd explain incase anyone else gets the same problem.
