Preview product redirects to Windows sale page

Hi everyone,

When I add a new product and want to preview it before I publish it the preview link redirects into a Windows selling link. What is wrong? The site works, I can publish the product just fine and when it is published the preview link works just fine and the product shows normally on the page. It is just when the product is not published that I am being send to this sale site. See screenshot: https://www.dropbox.com/s/cs0eb9orqt1bv77/Sk%C3%A6rmbillede%202016-11-09%20kl.%2017.07.13.png?dl=0

I also can’t seem to delete my plugins and even though my user is Admin – a message says that I need to authorize this site to get upgrades or support for one of the plugins. I also dont have the menu under “Control Panel” that says “updates” anymore. What is happening?

Hope that anyone can help. Thanks!
