Folder Persissions Problem/#6441

I have installed Streber suscessfully and used CHMOD in FTP to set persimissions to all _folders (eg. _files) to 777.
However when I go to upload a file to a task I get this error....

WARNING: rename() [<a href='function.rename'>function.rename</a>]: SAFE MODE Restriction in effect. The script whose uid is 10004 is not allowed to access /var/www/vhosts/londonoasis.co.uk/httpdocs/pm/_files/prj12 owned by uid 33

WARNING: could not move uploaded file from './_tmp/uploads/error.txt.txt' to './_files/prj12/129.error.txt.txt'

It would appear that folders that Sreber creates itself withing these folders have permissions of only 755, which does not apear enough to write the uploaded files. If I go to the new folder and change permissios then this particular upload works.

Any ides why this is happening and what I should do to fix it?

say, streber creates a folder itself in _files
