Is there an error in the javascript console? Maybe an adblocker is interfering.

In console I get
/analytics/index.php?date=yesterday&format=json&idSite=1&method=SitesManager.getJavascriptTag&module=API&period=day Failed to load resource: the server responded with a status of 500 ()

I'm not using adblocker at this computer, also I have check another computer and the same.

Hm, 500 means the error is on the server, so can you please also check your php error log?

This is my log, for me looks ok (hmm)

This looks like the access.log of your webserver. As the error (probably) occurs in piwik, we'll need the php errors, which are either in the error.log of your webserver or in a seperate php log file

@maw2be Do you have an error in your error log?
