I just made a fresh install of SilverStripe CMS v2.3.4 on a Mac OS-X 10.6.2 machine running Apache and MySQL.
I followed the installation steps and after a few seconds I was able to browse a web site with Home, About Us and Contact Us pages.
Then when I tried to log on to the CMS i got a message saying that there was no user with that email. This was easily fixed by adding "Security::setDefaultAdmin("admin", "password");" to the _config.php, as OwenW suggested on this post: http://www.silverstripe.org/installing-silverstripe/show/272954#post272954.
I tried both Safari Version 4.0.4 (6531.21.10) and Firefox version 3.5.5 with the same result.
I cant get past this point so I can't really do anything...
Does anybody have the same problem?
