Admin bar not showing at all

Same here: toolbar is always hidden (viewing site as admin). Tried to activate default theme Twenty Fifteen, didn’t work. Activated theme Twenty Fourteen, didn’t work either.

In contrast to Knut links near the top of the page just work.

Btw
I have a sticky main menu, semi transparent, that gets a bit smaller when scrolling down – but always stays there on top. Can it be there’s a conflict?

Hmm, no that doesn’t make any sense, since I tried with Twenty Fifteen and Twenty Fourteen…

Found out some useful stuff. It’s all about the browser.

I’m running Mac OSX Yosemite 10.10.2

Trying the plugin in Firefox 39 it doesn’t work. Trying in Safari 8.0.4 it does work (though the animation is a bit jerky). Trying in Chrome 43.0.2357.130 it works a just a bit: the bar disappears, then -hovering over the top- it appears but doesn’t disappear again…

Hope this can help solving the issue ??

Hmm, in Safari it not always disappears again… Sometimes it does, sometimes it doesn’t…

I have no problems in Chrome 43.0.2357.132, but I do see the ReferenceError in Firefox. This needs some investigation.

Did you investigate yet? ??

Yes I have.
Solved the problem for Firefox.
Will release a new version the coming days.
