During my installation I have this message
Yet I have php version 5.1.3
I do not understand
To run Piwik you need at least PHP version 5.1.3
Unfortunately it seems your webserver is using PHP version 4.4.3-dev.
Please try to update your PHP version, Piwik is really worth it! Nowadays most web hosts support PHP 5.1.3.
Pleaz help thx !
