I've been using this for almost a month now, and I notice that sometimes I get randomly redirected to the aforementioned URL without notice or warning, and it's always a 404 error, obviously.

Here my .htaccess:

# File modified on Sat Feb 16 14:40:33 2013 by server# For security reasons, mod_php is not used on this server. Use a php.ini file for php directives# php_flag register_globals off# For security reasons, Option followsymlinks cannot be overridden.#Options +FollowSymLinksOptions +SymLinksIfOwnerMatchRewriteEngine OnAddEncoding gzip .gzAddEncoding gzip .gzip<FilesMatch "\.(js.gz|js.gzip)$">  ForceType text/javascript</FilesMatch><FilesMatch "\.(css.gz|css.gzip)$">  ForceType text/css</FilesMatch>RewriteCond %{REQUEST_URI} !^/index\.phpRewriteCond %{REQUEST_URI} !/ow_updates/index\.phpRewriteCond %{REQUEST_URI} !/ow_updates/RewriteCond %{REQUEST_URI} !/ow_cron/run\.phpRewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.xml|\.feed|robots\.txt|\.raw|/[^.]*)$  [NC]RewriteRule (.*) index.php

Looks fine as far as I can tell. What gives? Any suggestions here?
