I've got my website set up so that I receive an email notification every time an error occurs. After installing CuteChat, I'm now getting a LOT of emails with the following error:

Error Page: http://www.mywebsite.com/CuteSoft_Client/CuteChat/settings.js.aspx

Any ideas on how I can fix this issue?
