I have inherited a Magento site running CE 18.104.22.168 and I am currently trying to integrate Paypal.
I have entered the registered Paypal email address under Merchant Account, and have also filled out the Api/Integration Settings form, both in the Paypal tab of the Configuration page.
However, I am not getting the options as shown in the first screenshot on this page: http://www.magentocommerce.com/knowledge-base/entry/setting-up-paypal-for-your-magento-store#1
There is no option to enable any of the Paypal payment methods individually on the same page, nor does Paypal show up under the Payment Methods tab of the Configuration page.
I am unsure if it is the version I am running, or if I am missing something somewhere, as I have never done this before. Any help would be appreciated.
