New nopCommerce Installation in Hostgator shared environment

Hi, I am very new to nopCommerce. I am trying to install a fresh copy of nopCommerce v3.9 in a shared windows environment by Hostgator.
I am getting below error while accessing the website.

FYI..I have given all the required permissions to the folders. Can anyone have the solution or, workaround for this.

"....change the application's trust level in the configuration file."

See if this helps
