Unable to execute plugin php files

Yes I understand that, but if you run this plugin PHP file on antoher site that has the plugin installed it executes the file
http://wealthynetizen.com/wp-content/plugins/comment-rating/ck-processkarma.php

The point being that my plugin cannot execute itself because on my site it is bein redirected as an article or something?

I previously thought it may have been the .htaccess settings but they all seem fine

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

As far as the plugin developer is aware it isn’t a conflict and I highly doubt it’s anything to do with my theme…

I posted that I had checked with the plugin developer, the .htaccess file since that is a common problem and said that I doubted it was the theme.

It isn’t the theme because this problem started when I moved hosts which is something I stated in my first post.

I am happy to check anything and do need help but a generic “something in the theme” is neither helpful nor insightful.
