I would like to activate layered navigation in our multi-store magento 1.7.
As soon as I activate it in a category, the following exception appears in the error-log:
`Call to a member function setTemplate() on a non-object in /xxx/xxx/xxx/app/code/core/Mage/Catalog/Block/Product/Abstract.php on line 192, referer: http://126.96.36.199/bs_de/vaporizer/zubehor/arizer-extreme-q`
Doesn't matter if our custom template or the modern template. The code exits at the point where the first price block would be displayed. We didn't made any modification in app/code/core/Mage.
What is going wrong? Any help?
