Please help me modify ownership/permissions

I’m new to working with UNIX commands, and I need to do the following:

3.2 Set directory ownership to that of your webserver on all module directories and files - including data directory.

eg: chown -R www:www filemgmt_data

Set permissions on directories and files to 754

Need to allow write permissions for Webuser to filemgmt_data directory

I’m running Geeklog vs. 1.3.9 on my website, and trying to get a file management plugin installed. I have the plugin installed correctly and can upload files just fine, but when clicking on the uploaded file my users get an Error 403: Forbidden:

You don’t have permission to access /filemgmt_data/files/itf-wp1_1024x768.jpg on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

To see this in action, please go to:

Can someone please walk me through setting the various permissions and file ownerships that I need to do to allow posting?

Thank you,
