I found that piwik was blocked by Avira Browser Safety extension (antivirus extension)
Also, it was blocked by Blur extension - a tracker blocker extension.
Both, are very popular extensions…
Any way I can make the piwik code not be be blocked by those or similar extensions?
Hi there, just to add my 2 cent:
happened to me, too, Chrome/Win7 and Ghostery extension installed.
Whitelisting the Piwik made the error go away.
Cheers, Igor
