Which templates are you using?
Do you get a javascript error in your browser’s console?
Provide some more info

I tried more template, but the problem is general.
http://badski.emegjelenes.hu/ --> use blackwhite2 template in default (http://www.icetheme.com/).
I assigmented some menu to other template (Beez3, protostar, etc.), but it not detected.
I tried more browser, but the problem is same.

This menu use Beez3 template: http://badski.emegjelenes.hu/hu/teli-ajanlatok/siberlet-akciok.html

Tried to reproduce it on my testing server but it's working fine there.

I turned on the "show error", and I get 2 SQL Error (duplicate): http://badski.emegjelenes.hu/en/winter-deals.html

Duplicate this:
SELECT m2.language, m2.id
FROM badski_menu as m
INNER JOIN badski_associations as a
ON a.id=m.id
AND a.context='com_menus.item'
INNER JOIN badski_associations as a2
ON a.key=a2.key
INNER JOIN badski_menu as m2
ON a2.id=m2.id
WHERE m.id=207

And This:
SELECT c2.language,CONCAT_WS(':', c2.id, c2.alias) AS id
FROM badski_categories as c
INNER JOIN badski_associations as a
ON a.id = c.id
AND a.context='com_categories.item'
INNER JOIN badski_associations as a2
ON a.key = a2.key
INNER JOIN badski_categories as c2
ON a2.id = c2.id
AND c2.extension = 'com_content'
WHERE c.id =13
AND c.extension = 'com_content'

What does the "Duplicate queries" mean?

It just means the code could perform more optimised because it fetchs the same information twice from the database. It's not an error itself.

If I turn of "Search Engine Friendly URLs", it would work. But I would like to use "SEF".

do you have an .htaccess ?
is it the one from joomla or custom?

Thanks,
I solved!
The problem was: I used the iceShortCode plugin to themplate. If I disabled, it's work.
