应用促销规则类别时出现错误500

Question

I found what it seems a bug inside Magento (1.9.3.0). When i create a new promotion on my catalog, then I apply it on a category it work.

But if this rule is in relation with some product on customer cart, then this customer have an error 500 on all the website. It seems to be an infinite loop or something like that.

I try to disable all my custom module, same, but when I disable Mage_Checkout, it work again.

I found this : http://ka.lpe.sh/2015/03/28/magento-checkout-cart-500-error/ but don't work for me, same with the "patch" on comments : https://gist.github.com/piotrekkaminski/54529dadb0bc01a62a2d

Have you some clue or better : solution ? :)

Thanks

Check error log or enable error reporting. To enable error reporting, do following steps:

In Index page change the following:

error_reporting(E_ALL | E_STRICT);

to

error_reporting(E_ALL);

Set $_SERVER['MAGE_IS_DEVELOPER_MODE'] = true

and uncomment this line

#ini_set('display_errors', 1);

After getting exact error, it can be solved.
