Error processing ssi file code

Failed request log revealed something interesting. At some point, IIS created a web. After that, each subsequent page request failed to load includes because it couldn't "duplicate collection entry". Accidentally, ConfigExceptionInfo line for that warning in freb does not wrap properly in the browser.

When I removed that config file, pages render properly. My question is how do we prevent this from happening? Right now, our site is using Application Pool set with "No managed code" and Classic pipeline mode. Should we be using a single pool for static sites? The content you requested has been removed.

I've tried different application pools, but none of that has made a difference. These are the same permissions as on the other website that works. I've tried making the content of the include very simple, just a closing head tag and an opening body tag. Still no go. What am I missing? I'm just completely frustrated because the two servers seem to have the exact same configuration and one is working and one isn't.
