Error ajax after upgrading 1.4.4.0 to 1.5.3.1

[ramirez033]

Hello guys,

 

I have an ajax error, because in hte admin panel -> product, when i click to the link on the left tabs for example associations, i stay on the information tab.

 

The page is reloading, i can't see the ajax animation.

 

I have this error :

 

var no_related_product = 'Aucun produit associé';
 var id_product_redirected = ;
  Uncaught SyntaxError: Unexpected token ;
 var product_name_redirected = '';

 

 

 

Any solution, i'm lost.
