What version are you trying to install?
The UBB cannot lie about the error message. It is returning what the Operating System told it. The OS told it that the script did not have sufficient permissions to create a directory
You have some options:
- See what the permissions are on /noncgi/styles. If they are not 777, set it and every folder inside /noncgi to 777 and see if it errors out again.
- You could remove all files, upload the installation again verifying correct permissions before you visit cp.cgi to setup your paths.
- You could fill out a
support ticket and let Infopop Support examine your installation
If the first 2 don't work, then you should definitely use the 3rd option as further troubleshooting requires FTP access to your server.
