Problem with Ulitmate Tag Warrior 3.0.1

Hi,

I’ve just checked what is loaded at the startup of my page and I get 2 strange entries that are not loaded (404), both coming from Ultimate Tag Warrior:

https://****.com/wp-content/plugins/UltimateTagWarrior/ultimate-tag-warrior-ajax-js.php?ajaxurl=https://****.com/wp-content/plugins/UltimateTagWarrior/ultimate-tag-warrior-ajax.php

and

https://****.com/wp-content/plugins/UltimateTagWarrior/ultimate-tag-warrior-js.php

The files are there, but why WP is trying to load php files? If it’s ok and these file should be loaded what permission should they have?
