Hi in my ASP.net web app my hosting provider Hostgator said they did the following. I am not sure which lines they are referring to in my web.config file shown further on

Hosrgator's comment: "Finally I commented out the system.codedom section of lines 35-40, as that section is not allowed on shared servers, due to the security implications of allowing custom compilers.  Once all of this was done the site started to load properly."

my web.config file:

<?xml version="1.0"?>
