Data not recorded in PIWIK



I am new to PIWIK , I installed it on EasyPHP-DevServer-14.1VC9. I created a site and placed the javascript tracking in my the theme of my application.

When i refresh my application i see the request is sent to PIWIK (access.log is updated with the request). But the action is not recorded into PIWIK database.

Could anyone help me to solve this. Thanks in advance.
