mod_rewrite saying "No input file specified."

[tiki]

Ok I have tested this on two sites/hosts/domains. One works the other doesnt.

It doesnt work here:
[a href=\"http://www.mileswjohnson.com/contact/\" target=\"_blank\"]http://www.mileswjohnson.com/contact/[/a]

But then this works, but isnt showing header and footer
[a href=\"http://www.mileswjohnson.com/contact\" target=\"_blank\"]http://www.mileswjohnson.com/contact[/a]

And heres the site were it does work
[a href=\"http://www.inferiaefashion.com/personal/Portfolio/contact/\" target=\"_blank\"]http://www.inferiaefashion.com/personal/Portfolio/contact/[/a]

It does that for all the pages.
