I need to set up some administrators however when I click on the Security tab i get this error

Fatal error: Access to undeclared static property: ViewableData::$db in /var/www/vhosts/xxxxxxxx.co.uk/httpdocs/sapphire/core/Object.php(324) : eval()'d code on line 1

I also get the same error for forum members and mailing lists within Security

The site is almost ready to go live and this is a big issue that i need to resolve soon - how can i fix it.

I am seeing the same error. I tried a fresh install of SilerStripe 2.2.2 but the bug is persistant. Is there any specific requirements on the server side to run the security section. I am using an Ubuntu server.
Need more details in server? Any ideas on what's wrong? Thanks.

I did two things.
First I increased the memory_limit in /etc/php5/php.ini from 20M to 32M. This was recommended by the Silverstripe install page.
This did not make the Security tab in my 2.2.2 site work.
Then I installed Silverstripe 2.0.2 sr2 the same way, on the same server.
The security tab in 2.0.2 works fine now.

A bit closer..:-)

Seem to be discussing this with myself :-))
Just like to add; the bug(?) is also affecting the possibility to produce Reports.
I am receiving this on a blank page:

Fatal error: Class 'Report_StatsReport' not found in /var/www/mysite/cms/code/ReportAdmin.php on line 70

So two problems that perhaps are related.

This bug only affects PHP 5.1.2. Would it be possible to upgrade PHP to 5.2.x?

I'm also getting this error:

/var/www/vhosts/domain.co.uk/httpdocs/sapphire/core/Object.php(324) : eval()'d code on line 1

The php version is 5.1.2, I'm on a VPS and my hosts are unable to upgrade to 5.2.*, something to do with a conflict with the plesk control panel.

I'm I able to get Silverstripe working with php 5.1.2?
