Fix magento 1 extension's bugs - project for Le

We are using an extension named "Popup recent orders" for showing recent purchased orders for customers on our website. This plugin has 2 bugs need to be fixed. Firstly, when the product is on the display list of the plugin, and this product was disable at the back end, the plugin will show PHP error. We would like to update the plugin to behave that when the product is disabled, the plugin will skip and don't show this product. Secondly, when customer purchased a sub product of a configurable product and that product was setting as not showing individually, this plugin will still showing this sub product with its actually product link which will link to a 404 page. We would like to update plugin to show the master configurable product link in this case.
