Getting error with the web config file

I am trying to implement wordpress template on my windows server site. As soon as I tried to run the page I got an HTTP error 500.19 indicating me that my web config file is missing declaration. Here is what its saying:

The configuration section 'phpNet' cannot be read because it is missing a section declaration

My web.config file is:
