Content list tab in Configuration not clickable

Hello,
I seem to have an issue with FC Configuration panel.
I'm not able to select "Content list" tab, and the last four tabs can only be opened if I go to "Options" and then, for example, to "Backend manager".
I noticed this problem on version r1841, so I updated to version r1857, but the issue persists.
Do you know if this is a bug or something?
Here is the live url of the test website: bit.ly/1cUBxPs
Please tell me if you need backend access, I can send via PM.
Thanks!

Hello, I have the same problem. It seems to be due to the use of the translation component of the Italian language (I'm Italian). In fact, by setting the English language that solves the problem. Try it yourself to reset to English, and let us sapere.Il why all do not know.

Hello

dario,
thanks for feedback !!

i ll install italian translation, to check why

I've tried to turn on the English language and it does work. So the problem is actually with the Italian language. Are there any updates on the issue?
Thank you so much!
