Service Policy

Our stated prices for all modules we install are based on installation into the default platform configuration. We always ensure your logo and basic color palette are in place when we install a plugin. However, any additional "custom" styling, design work, or derivitive tasks generated due to a site's non-default configuration could require additional prepaid programming hours.

This plugin is open source and requires ionCube Loader v4.4 or later to be compiled with PHP in order to install and upgrade the plugin. All orders are automatically subscribed to the billing frequency selected at the time of purchase. Recurring billing can be cancelled at any time. Once your license has expired, a new license will be required in order to continue using the plugin.
