If you are experiencing permissions errors, please try the following:

Setting Permissions on Windows Servers:
In Windows Explorer:
1. Right click on the root directory of your site and select "Properties".
2. Go to the "Security" tab.
3. Select “SYSTEM” and click “Edit”. You may need to do this for "Guest Accounts" too, if this does not work.
4. Make sure Deny Write isn’t checked, or select "Full Control". Also, make sure that this applies to all files and sub-directories.
5. Hit “OK”.
Basically, you need to make sure that the "system" (or possibly "guests") have "write" permissions.
Please note: you cannot change file permissions through FTP on Windows servers. If you do not have direct access to your server’s file system, you will need to contact your host and tell them to go through this process.

We are working on a solution for permissions errors on apache servers, which will be out in v1.2 in the next couple of weeks.

As of v1.2, you should be able to set your FTP information in order to work around permissions errors.

A lot of servers that I've encountered do not run PHP as the user, but instead as "nobody" so that it doesn't have as many privileges. In this case you either need to use the FTP option (but make sure your server has FTP enabled for PHP--the one I'm working on doesn't) or set the file options to 666 for web pages and 777 for directories (such as the image directory or files directory)
