Creating a package leads to an 500 Server Error

[Peter Pastoor]

Hi again,

When creating a package of 2 products, I get an

500 Server Error

every time in the store that I can only solve by a backup. What can be the problem here?

I use version 1.7.4.2.

Every time it seems to have something to do with a certain category. When I make a package with a product from category 1 as an example and I place it in that category it goes wrong. I make a package in another category, it goes well. I make a package with products from category 1 and put it in another category, category 1 is going down with the server 500 error.
