Iâm having problems in adding configurable product in cart on product detail page. After clicking âAdd to cartâ button I get a message saying that the product is out of stock. But on the product detail page I also display âIn stockâ value and the product is in stock. After checking the backend I can for sure say that all products are set as âIn Stockâ and âEnabledâ. Adding simple products works with no problem though. So this problem refers only to configurable products.
When I try to add new configurable product via Backend and assign Categories to it, I get this error: Invalid method Mage_CatalogRule_Model_Rule::applyAllRulesToProduct(Array (  => 3546 ) )
Maybe that’s also related to my “Add to cart” problem.
Iâm working on Magento CE v126.96.36.199.
I would really appreciate it if you could help me solve this.
