I´m doin' right now an final installation on a hosted server, but the only error that keeps apearing is:

File system permissions problems found.

The Data folder beneath the root of the web site is not writable by the ASP.NET worker process.

You need to make this folder and all its child folders and files writable before setup can proceed. mojoPortal needs this to be able to write search index files, error logs, image gallery uploads, and other important features.

Right Click the Data folder in Windows explorer, choose properties and go to the Security tab. (On XP if you don't see the security tab then google for XP Simple File sharing to learn how to make that tab appear.) On XP you typically need to give write permission to ASPNET user while on Windows 2003 you need to give it to IIS_WPG user.

Obviously, instructions are a little different on Linux/Mono but the same principle is true, the Data folder and all its child objects must be writable.

Folder Details
•The Data folder is not writable.
•The Data/Sites/1/ folder is not writable
•The Data/Sites/1/systemfiles/ folder is not writable
•The Data/Sites/1/index/ folder is not writable
•The Data/Sites/1/SharedFiles/ folder is not writable
•The Data/Sites/1/SharedFiles/History/ folder is not writable

Can you help me?
