Hey SilverStrippers,
Here's one that's got me stumped....
I've extended the Member object using DataObjectDecorator for a site I'm working on.
If I declare this extension in mysite/_config.php using Object::add_extension('Member','MemberExtension') - SilverStripe won't allow me to access the CMS. It just keeps telling me to login. (Yes I'm using setDefaultAdmin)
If I comment out the Object::add_extension line it lets me access the CMS fine.

Yes the session.save_path in Php.ini is writeable!
