i joined quickpay set it all up and made the file To use credit card plugins, you need to create a key file that contains unique encryption key for your website. It is necessary even if the plugin does not store sensitive information. In a text editor, create file with the following content (one-line, no spaces before opening <?php): <?php return 'qk6PhNJt3bXc4gBdKYwFIQTsAbuPMQCRYEXYOgY4UPwyCNVfD2g6fCZgxY9TXuguor3jGgO3PHeYJF'; save the file as key.php, and upload to amember/application/configs/ folder. This warning will disappear once you do it correctly. KEEP A BACKUP COPY OF THE key.php FILE (!) when i click save, then thing gives me a new code, tried for 20 mins, why wont it save?
