I have the latest piwik 1.8.2 installed using the piwik.js from this install, it loads and works perfectly in firefox 14 and IE9, but in chrome 20+ it fails to load, with no real error given.
I am attaching screenshots that show the same page in chrome and in firefox. As you can see chrome fails to load piwik, but firefox works. IE9 is the same as firefox, I just can't get a screenshot for IE easily.
This was all working perfectly on a piwik 1.7.x install, it's only been an issue since upgrading piwik to 1.8.2

Delete browser cache & try again? works for me on chrome20
