[Fixed] Installation Problem: PHP Session Support

Hi,

I'm trying to install my fourth instance of WB on a new hosting account with the same firm as hosts all the others. With this host (asmallorange.com), I need to use PHP5 to address file permissions issues. If I use PHP4, then the WB installer reports session support enabled but fails the permissions. When I try to install WB under PHP5, I get the green light on the permissions but a red "disabled" for PHP Session support. I have contacted the hosting company's support group and they have confirmed that PHP5 and session support is enabled and provided a phpinfo page in my account to confirm it is.

Here are the specific error messages which show in the error log:

Code:

[22-Jan-2010 03:08:05] PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: open(/tmp/sess_f97cbf94fe36b57dc7be6f5573ff955d, O_RDWR) failed: Permission denied (13) in /home/cshweb/public_html/install/index.php on line 29

OK, so it looks like there may be an issue with the /tmp file and permissions. Where is this

Code:

session.save_path

being set? Is this something I can change in WB or is it a configuration issue with my hosting company?

Or is that error just a symptom of some other problem?

Thanks,
