Re: Cannot reindex 'Category Products' Index Process Information

I have tried to reinstall three times and still get the same error. All the other indexes is reindexing, but not category products for some reason...

Re: Cannot reindex 'Category Products' Index Process Information



I just solved this with help from the Azure support. The problem appears in the setup of the Magento-site where no root category is choosen. So what you need to do i choose one. Se my steps below.


Go to Admin Panel - > System -> Configuration and then click on Manage Stores on the left and under the Store Name click on Main Website Store.


And choose the Root Category to Default Category. (by Default you may see –Please Select a Category--)


Then save and test to reindex. This should fix the problem. It did for the support team, and it did for me.


The product group is notified to change the setup process so this will be set directly after install.
