$product->link not correct anymore after upgrade from VM 2.0.20b to VM 2.0.24

[csg22]

so you use external on some products and internal on others?

Hello,
I have the same problem. I use only external url's for product_url.
Interesting is, I added around 100 products in one category, the product detail links are fine there.
I added 16 products to another category and product link and product url are mixed.
In both cases url contains 'http://'
Any Idea?
Thanks!
