Hi,
It's promised in Matukio features: "Easy payment via Paypal and other payment Systems (Like cash, banktransfer, credit card, invoice, UPay and more)"
Sorry, but I can't find in the back end where to adjust Paypal, I can see only bank transfer ...
of course we support PayPal and even more then listed there. The settings can be found in the fitting plugin settings. Just select the Joomla Plugin Manager and select group payment, then you should get the list of available payment plugins (including paypal). Just click on it to configure it. More details can also be found in the documentation.
