Hi, thanks for replay my question.  I found this bug using the spanish version ( the mexican spanish works fine ) of the router administrator web page, the engish and every other language version´s works fine.

Here both full screen shot´s.  First, the english version working, second, the spanish version, not working.

Look the "undefined" in place of "Wireless Schedule" menu option, and the page charging forever ( bloked ).

Sorry for my english, it´s not my first language.  

Thanks again for your answer.

Confirmed

Does not load some menus using the Spanish language.

Take a look at this link and test the bugs I reported and confirm these bugs.
