I had a Magento 2.0.2 and upgraded into 2.0.4 version through Web Setup Wizard. Everything worked fine, and the frontend and backend work properly, but when I'm trying to access the Web Setup Wizard from the back-end, I get an error:
"Welcome to Magento Admin, your online store headquarters. To use the Magento setup wizard sign into your Admin account and navigate to System => Tools => Web Setup Wizard"
Can someone please help me fix this. Thanks
