one solution for eprentice permission problems
If you're having trouble seeing stuff you've uploaded to eprentice, it's likely because file permissions don't seem to be getting assigned correctly within eprentice right now. I'm taking care of the problem by using Filezilla to reassign permissions after uploading files. (Once a file's permission is correctly set, it will stay correct on subsequent file updates.)
Filezilla is a free, stand alone, PC only, FTP program. You can get it here: http://sourceforge.net/project/showfiles.php?group_id=21558&package_id=15149
Easiest choice from that screen is the .exe file.
Once you've downloaded and run the file, FileZilla will be ready to go. You can just fill in the ftp address, username, and password at the top to connect (or you can go to File->Site Manager to set up a connection you can reuse later).
Once you're connected, navigate to the eprentice folder where your files are. Note the permissions to the far right of the folder/file names. To work correctly, they should read: -rwxrwxr-x. Right click on the name of any file needing to be changed and choose "File Attributes". Change the numeric value to 775 (or click all the permission boxes except "write" under "Public Permissions". That should do it.
On a Mac, you should be able to accomplish the same thing with Fugu or maybe Fetch.
