This looks exactly right to me.  You might try removing the
RewriteBase line and see if that helps.

Also, remove any index.php file that you may have in your
document root, and see if the url


works (you should see the PmWiki home page if it does).
If that url doesn't work, try creating a _completely empty_
index.php file and see what happens.

I'm also wondering if the Apache webserver at GoDaddy is doing
the equivalent of "AcceptPathInfo Off" and returning the 404
error before ever trying the .htaccess or the mod_rewrite rules.  
You could try adding

    AcceptPathInfo On

to your .htaccess and see if that resolves the 404.

Also, do you happen to know what version of Apache is being used?
(You can set $EnableDiag=1; in local/config.php, then use ?action=phpinfo
to have PmWiki report the Apache version and configuration.)

Lastly, perhaps you could send me (privately if you want) the
actual url of the site so I could take a look?
