PHP Linking issue (Archives)

For some reason, the plugin “Custom Post Type Archive” links incorrectly – instead of posting http://www.example.com/?m=201102&post-type=presentations, it posts the url like so:

test.example.com/:/test.example.com/?m=201102&post-type=presentations

The weird part is, when you hover over the link in the Custom Post Type Archive, it shows the correct path; it just doesn’t direct properly…so I’m sure it has something to do with PHP but I tried tweaking the code and nothing’s working. Any help would be greatly appreciated! Thanks.
