Unable to load config.json error...file exists on server

[KenBuja]

I am getting the error "Unable to load config.json?wab_dv=2.8 status: 404 and an error in handleAs: transformation of response" on a web site I've deployed. It's a duplicate (with a few minor changes) of another site that I've deployed that works. The config.json file exists on the server for both sites.

Both sites work properly on our staging server.

Why would I be getting the error on the production server for one but not the other?

cheers, figured it was worth a try:)

The web.config files for both sites are identical:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.webServer>
        <staticContent>
            <!-- Configure site to serve JSON files -->
            <remove fileExtension=".json" />
            <mimeMap fileExtension=".json" mimeType="application/json" />
            <!-- Configure site to serve font files -->
            <remove fileExtension=".otf" />
            <mimeMap fileExtension=".otf" mimeType="font/otf" />
        </staticContent>
    </system.webServer>
</configuration>‍‍‍‍‍‍‍‍‍‍‍‍‍

Is there something else I should look at in the files?
