I have installed everything without problems to try the cms in localhost in my pc. But i cant login. With phpmyadmin I have seen that my user and password are ok and I dont know where is the problem.

Can you help me?

Thanks.

No, I'm not using an older version. My PHP version is 5.1.2.

have you tired rebuilding the database - http://localhost/whateverSiteName/db/build/?flush=1

Heres a list of common problem fixes - http://doc.silverstripe.com/doku.php?id=common-problems

Okay I have just spent two hours typing my damn user id and password to no avail. I am running WAMP server on a local windows machine. I triied all of the flush remedies, the new re-build files and shut off zone alarm completely....
It takes me to the default homepage to login:email/password.

So, I know the install is fine. My password is the same and I checked the files and there it was clear as day. Now what? I run wordpress and joomla just fine on WAMP located along with Silverstripe in my root folder. So if someone does not help me I'll just have to go back to the other guys.......WP & Joomla. too bad I wanted to check this out. Maybe you should do something so it;s not such a pain to run...........IMHO

Peace,
Ken
