问题
Hi, I am trying magento 2 and struggling to install the new theme. Because Design Theme is not showing under Stores > Configuration > Design.
回答1:
It has been moved to Content/Design/Configuration
回答2:
Yes It has been moved to Content/Design/Configuration. check screenshot for more clarification
Then you can select specific store if you have multi store. click edit action and in new window you can find search engine robots setting.
回答3:
In Magento 2.0.x, you can configure the theme in Stores > Configuration > Design.
However, from Magento 2.1.x, this configuration is relocated in Content > Design > Configuration. Edit the theme currently in used, and select the newly installed theme.
