Some Problems with Piwik

Hello,
some days ago I installed Piwik on my server.
Works almost fine. But there are some problems.

After i already installed Piwik, the server was updatet from PHP 4.x to 5.x. Now when i want to login i get an error with PHP 5. There’s no error when i activate a PHP 5 CGI Handler as PHP replacement on the server via .htaccess.

Hi webhopper,

Welcome to the Piwik community forums!

What PHP error do you get? Please provide me with the error description.
