Hi there,

In IIS manager, go to Errors and enable detailed errors. This might give you a few more clues as to why the error occurs.
IIS generally gobbles up the errors unless you tell it not to, or unless you browse the site locally on the server.

FYI, I've installed SilverStripe on many IIS 7.x with SQL Server 2008 installations using the installer and it's been a smooth process.

Check that you've got the IIS URL Rewrite module installed too. Find it here: http://www.iis.net/download/URLRewrite

Hope this helps!

Cheers,
Sean

Thank you for your answer, Sean

Since 2.4 is a new release I report my conditions. It might help to get it as clean as possible.

2.3 ran (almost) perfect. But before I wanted to go about a strange behavior I wanted to upgrade. And that is the point when I got stuck and had to turn to this forum. It might be that the installation (Webinstaller) works fine. But if you upgrade you encounter problems. So I did a clean install on a machine that 2.3 was running fine.

after extensive trying I got Silverstripe to log. The logflie paths should look something like this: "/inetpub/log/ss.log" starting from the drive where PHP is located, so in most cases c:. "/log/" will not work. There's got to be a logfilename! Maybe a note in the config file would save time for others.

the Logfile states: " Error at \sapphire\thirdparty\Zend\Cache.php line 208: Uncaught Zend_Cache_Exception: cache_dir is not writable"

finding out with procmon I can see that PHP tries to access c:/windows/temp/

concluding ss tries to cache files in c:/windows/temp/

so how can I set the cache_dir ?

greetings!

In Windows Explorer, browse to C:\Windows\, right click the Temp directory and select Properties.

Click the Security tab, proceed through any message of warning and give the Users group read and write access using the checkboxes.

PHP / SilverStripe should now be able to write into C:\Windows\Temp\
