Simple fix

I have a script that is giving me the following error. There is a "user" tab in the "back end" dashboard that is supposed to list users. However, when i select it, i get a 500 server error. The script has a debug so when i selected it, i got the error i have included. Its probably a line or two of code that needs to be changed. The script did not cost very much and their support is non existent. Would appreciate some help or advice. Thanks
