(Plugin) Promo code does not applies to

(Plugin) Promo code does not applies to “Upgrade Listing to Featured”
After several tests, I notice that promo code does not work for “Upgrade to Featured” from user’s account area.
Every time I’m trying to apply promo code, the system automatically redirects me to a payment gateway (PayPal) with $0.00 amount.

not sure if this helps http://www.flynax.com/forum/showthre...n-Code-problem

Thanks Chris,
It works now.
I used the information you provide at your link.

---------------------------------------
To resolve the issue you have to:

1. Ftp to your server;
2. Go to Includes subdirectory;
3. Open a file called upgrade_listings.inc.php; and
4. Add a string:

$rlHook -> load('phpListingsUpgradePlanInfo');

Under the following code:
/* get plan info */
$plan_info = $plans[$plan_id];
$current_plan_info = $plans[$listing['Plan_ID']];
