After upgrade to 1.8.4 Live Vistor Widget is broken

After upgrade to 1.8.4 the Live Vistor Widget is broken and looks like the following screenshot shows:

The Live-Widget tries to request the following url’s - which does not exist - over and over again:

piwik-domain.tld/e 404 (Not Found)
piwik-domain.tld/M 404 (Not Found)

Any suggestions on that would be nice!

can you please send me an email at with your piwik URL + login + pwd + bug description ? i’ll take a look thx

Thank you for your prompt reply, please check your email.

I’ve noticed now, that the whole gui isn’t displaying any data for today. The data still get’s recorded to the database. Everything is ok for yesterday - except for the Live-Widget.
