We have defined a URL for PayPal transactions that are failed or cancelled.
Sometimes you want your own page for some reasons, that wil be very easy create.

Let's take a look how to create a return URL for PayPal, it's small fix.
First you will have to create a proper page in Joomla! (article or something)

Open the next file:  ../components/com_ticketmaster/views/payment/tmpl/default.php

Replace on line 38:

$cancel_url = JURI::root().'index.php?option=com_ticketmaster&controller=transaction&task=cancel';

with an url you like. JURI::root(). needs to be there, it defines your domainname.
Example for can be:

$cancel_url = JURI::root().'rd-ticketmaster/ticketmaster-support/comment/53-return-url-for-paypal.html';

It will reirect your users to this page :) Make the URL you like.
