FallbackResource causes net::ERR_INCOMPLETE_CHUNKED_ENCODING

Question

When I use a .htaccess that contains just this line:

FallbackResource index.php

I get this error on Chrome only:

 net::ERR_INCOMPLETE_CHUNKED_ENCODING

The error appears only when access the root directory where the .htaccess is located.

IE, if .htacess is in www.mysite.org/admin then the error only appears when I type that exact URL in the nav bar.

If I go to www.mysite.org/admin/index.php or www.mysite.org/admin/some-user-friendly-url there is no error.

The error is really annoying as it delays the page load by several seconds and makes the page fail to execute some JavaScript that should happen on page load.

Like many others with this error, it only happens in Chrome. Solutions from other posts were of no help in my particular case.

Answer 1

Add DirectoryIndex directive to .htaccess file before FallbackResource. This fixed the problem for me.

DirectoryIndex index.php
