Hello everybody,

This thread is dedicated to all those who use Coupon Code Plugin and have a problem on the Upgrade listing page.

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']];

Thanks.
