[TYPO3-install] Fresh Install --> File permission error when adding new page content

[Chris Jensen]

Hi,

I'm a Typo3 newbee and have just installed the base typo3 package on my 
server. The frontend and backend tools both seem to be working and there 
are no critical errors displayed in the Install Tool (under "Basic 
Configuration").

I can add new pages (via the backend tool), but when I try to add new 
page content, I get the following error message: "File not written to 
disk! Write permission error in filesystem?"

The problem is that the file permissions on the typo3conf, typo3temp, 
fileadmin and uploads directories are already set to 777.

After checking through the forums and documentation, it seems that the 
problem might be that PHP is in safemode. If that's the issue, who needs 
to be set as the owner of these files/directories to make them writable? 
Is there any way to make safemode work or do I need to talk my ISP into 
turning it off?

I'd appreciate any insight... I'm looking forward to learning more about 
Typo3, but this issue is presenting kind of a bottleneck.

Thanks,
