Thread:Project:Support desk/Content Encoding Error after Migration/reply (4)

The problem is that the server is sending the HTTP header  as a response, but the content is not being encoded in gzip, it's in plain text (or plain HTML).

Your server is misconfigured. It's sending that header but it's not compressing the content. If I send a HTTP request without an, the page looks fine, since the server doesn't send that header.

The page that returns is a HTTP 404 error page anyway so it's not a misconfiguration of MediaWiki.
