Features / Usability

Hey folks,

I've set my userfiles upload feature to upload to a directory rather than the database. However, when I try to upload a file, I get this error

b>Warning: fopen(/home/files/terrabuz6c36bd6d5132ffe3a54fb4ce093dd32e): failed to open stream: Permission denied in /var/www/html/tiki-1.8/tiki-userfiles.php on line 59
-^

Incidentally, the directory is the same directory that the file and image galleries upload to (successfully).

Can anyone shed any light on this for me?

Thanks in advance
