add to cart button missing with some browser

[sdossantos]

Hi all,

 

I have migrated a prestashop 1.4.9 to 1.5.2, since migration, the add to cart button missing with some browser.

 

For example it is ok for me on chrome and on IE 9 but not on firefox, for an other computer it is ok also on chrome, but not on IE8.

 

I have check the variable PS_CATALOG_MODE on database equals to 0.

 

I have added some comment on product page, the value still to 1 on firefox on IE8. I dont know why ...

 

 

Sample code on

 

IE9 : <!-- add to cart form PS_CATALOG_MODE= Group= isset= product_quantity=99 > 0 -->

Chrome : <!-- add to cart form PS_CATALOG_MODE= Group= isset= product_quantity=99 > 0 -->

Firefox : <!-- add to cart form PS_CATALOG_MODE=1 Group= isset= product_quantity=99 > 0 -->

 

have you a fix to solve it ?
