Undefined index: base_price after update to prestashop 1.6.1.13

[Crazyweb]

I recently updated my store to the latest 1.6.1.13 prestashop and discovered an error.

 

Undefined index: base_price in /home//www.------.com/cache/smarty/compile/f1/77/e3/f1771.file.product.tpl.php on line 675

 

The issue is the product price with discount quantity.  When quantity is 1, price shows correct. But when the quantity increases and a quantity discount should apply, the price drops to 0,00. If you add the discounted amount in the basket, the basket will show the correct price incl. discount.

 

I tried to file in smarty/compile, but this does not help as it gets regenerated. And shows the same issue

 

I would like to solve this error but dont know where to find the solution.
