I just installed MediaWiki 1.5.2 (stable) on
Win 2003 server

• MediaWiki: 1.5.2
• PHP: 5.0.5 (isapi)
• MySQL: 5.0.15-nt

And for some reason session folder was not created. Everything worked fine
except that only authenticated users could not save changes. It kept bringing up
the preview, without giving any errors, and kept trying to set the
$_SESSION['wsEditToken'] = $token; (user.php)

but because the server did not store sessions, it kept getting reset.

A check is needed in either the initial setup or as part of page save, and a
message should be displayed.

Thanks!

Version: 1.5.x
Severity: enhancement
