I have followed the rules to install you plugin in WHMCS.
I at first tried a live test then later I switched to the Demo trial. Everything goes straight until i reach the stage where i click on the payment button in the invoice. At this stage, when I click I am redirected to a "404" page with the words
"Oops... Page Not Found! Sorry the Page Could not be Found here. Try using the button below to go to main page of the site"
Here is the URL that am redirected to:
frankhost.net/modules/gateways/pesapal/iframe.php
I don't know why this happens. I need help and thanks in advance
