Coding error with version 2.5 with User Photo plugin

I have used this plug in an when I try to up load an image I get this error page:

message Warning: mkdir() [function.mkdir]: Unable to access /mounted-storage/home43a/sub002/sc32306-YRBZ/in-business.org.uk/blog//wp-content/uploads/userphoto in /mounted-storage/home43a/sub002/sc32306-YRBZ/in-business.org.uk/blog/wp-content/plugins/user-photo/user-photo.php on line 279
