Hi
You can ask your provider to give u the tar file of the theme then u can do :
1) Remove the links to those functions
2) Remove all the files that are linked to in 1) -- Don't forget to have a copy handy in case u r thinking about adding them later on
Maybe adding your own touches as well
Then you can send the tar file to your provider to install the m for you if you can't/don't have access your self.
