Fix Bug on Prestashop Site - Caused by Faulty Module

I tried installing a module in Prestashop 1.6 for ShippingEasy. The module didn't function and we noticed this error caused when setting up an order in the backend, there is also an error displayed when after your submit an order on the frontend. They both occured at the same time I believe both issues should clear once the code is resolved. The modules was disabled, than uninstalled a couple days ago and the error persists: Notice on line 1736 in file /home/esdguns2/public_html/tools/smarty/sysplugins/[login to view URL](157) : eval()'d code [8] Trying to get property of non-object
