Error edit product 1.6.1.17

[angular]

Hi! I have a Prestashop multistore (My prestashop version is 1.6.1.17, I updated my site to try resolve this error, but it no fixed).

 

The problem is that since the las week when I am trying edit and product, the first page appears ok, but then I click in another section (for example price, quantity, images...) of product edit page, and the back office show me the dashboard...

 

I don't know what is happening, I disabled all external modules and updated from version 1.6.1.14.

 

In addition, I cant create a new discount voucher, I click in the tabs to config it and nothing happend, the screen not change... Only in the url appears "#" symbol when I click in the actions or conditions tab.

 

My hosting have php 5.6

 

I need help please. Thanks a lot.
