Forum OpenACS Q&A: File Manager

I have installed the file mangaer package on my version of OpenACS 4.6.3. I am using Red Hat Linux 8.0 and PostgreSQL 7.2. I am having some problems with the package. On the navigation bar, the main folder is the "www" folder under "/web/myservice/www". I dont if that was the only folder with files we can edit or if we could edit files/pages under other packages. I was successful in creating a new folder but when I want to add a file to the new folder, I get this error:

Could you tell me what is wrong with this picture. I also tried to edit a file I have stored under the "www" folder. After modifying, and filling out the comment box, when I click "commit" this is what I get:

We had some problems processing your entry:

    * You must supply a value for file_content
    * You must supply a value for path
    * You must supply a value for message

Please back up using your browser, correct them, and resubmit your entry.

Thank you. 

So what is going wrong. Am I not using this package correctly or are these known problems? Thank you for your help
