I've been fighting with this issue for days now and I can't hold it any longer.
We have Magento Community Edition 1.9 running with a extension from MageWorld Advanced Product Options.
It was an expensive extension which apparently doesn't work properly on 1.9. For days I ve been trying to copy the product options from one product to multiple because it would save me a lot of time and the extension should automatically support it.
But it doesn't work, isn't it there any easier way to copy custom options from one product to multiple?
