Piwik Installation is done But No data is shown even after visits

I have setup piwic on apache2 … And have completed the installation process of 8 steps .

I have even included tracking code in my website But its still not giving any data for visits.

I have tried the piwic service and it gives me the visits data.

So is there any extra configuration that i have to do for apache2 ??
