Hi,
I just downloaded the latest SilverStripe v2.3.0 to install on our hsoting space. I have found 2 issues, the 1st was the protected $baseDir; at line 526 of the install.php, this was generating an error that wouldn't start the install script. I commented this out and then the next issue I found is that our webhost company put a - in the database names i.e. when I created a database silver it will call it web056-silver . The install process kept stripping the - out of the db name and therefore would then refuse to find the db to continue the install process.
If anyone has comments or solutions to these issues I'd love to hear them as the CMs looks great and I can't wait to actuallly get it installed and play with it properly.
