I posted this issue once, but the post has disappeared?
When one of our stores was upgraded to 1.5.0 (and now 126.96.36.199) Configurable products aren\\\’t possible anymore.
The Configurable itself can be created but none of the functions in Associated Products creates the link between the Configurable and the Siimple Product. The Simple product actually is created but never connected.
There\\\’s a significant difference;
Simple products created before the upgrade can be associated to a new Configurable product and existing ones.
Simple products made after the upgrade can\\\’t be associated to any Configurable product.
There must be a difference in how the products are stored, I tried to run the Adminhtml from 1.4.2 after the upgrade and then the code complains about EAV-tables.
It seems I have to go back to 1.4.2 as the web-shop is nothing but Configurables… :(
