Multiple Buttons not reacting when clicking (for example Save, Dashboard, Visitors etc..) (3 replies)

Good Evening,

Since the update of my Piwik Server ( to 1.11.0 and 1.11.1) I've been having an interesting phenomena.

I have configured 2 users + anonymous user on my piwik server.

None of them can see actually the Dashboard, and for none of the the Menus "Dashboard", "Visitors", "Actions", "Referrers" or sub menus reacts when clicking on them.

Not even the "Save" Buttons are reacting on the Settings side.

Do someone know how I can solve this problem?

Thanks in Advacne,

Daniel
