Here's the setup.
I've got a directory on a site iodai.com/live/
I placed an .htaccess file within that directory; here's the contents.
----------------------------
Options +FollowSymLinks
RewriteEngine On
RewriteRule .* publish365.php [L]
-----------------------------

This works as intended. Everything gets forwarded to the php processing page. eg. iodai.com/live/11.html
will get forwarded to publish365.php, and it gets dealt with there.

The problem i'm having is this; if I navigate to iodai.com/live
(ie. without the trailing slash), I get an error 400 Bad Request.

example site iodai.com

Other folders without a .htaccess file work fine.
I tried putting a DirectoryIndex directive into the htaccess; no joy.

Any help would be appreciated.
