Piwik doesn't display second web site statistics

Dear Sir / Madam

I installed Piwik on my web site ( Joomla3 ) and work it good. then i added another web site ( Joomla 2.5 ) on Piwik but it show following message : " No data has been recorded yet

No analytics data has been tracked for this website yet. Please set up the JavaScript tracking code on your website and refresh the page.

I copy+ paste Tracking code to second web site but it show above message yet.what is the problem.should i edit Tracking code for second web site? Both of tracking code are same.
Please help me.

Make sure that the java script code you have entered is installed properly because I used Gostats & while installing it I just entered its code which I had taken from its site & still I’m getting every detail of my website.

Hi there, see also: Visits from search engines or campaigns are not recorded, Piwik shows "There is no data for this report" for all Referrers reports. - Analytics Platform - Matomo

Hi matt,

I found this link is very useful but I used Gostats to track visitors & every detail of my website. Also it gives me accurate report in a real time.
