I am facing an issue that whenever I preview any page from the Sitecore content tree, it displays a blank page. Although the pages have the page design set correctly and are displayed correctly on the published site (CD).
Sitecore 9.1.1 in a scaled environment.
Any idea what might be causing this issue?
Update: sc_site query string parameter is not resolving the correct current site name. The issue is that its always getting sc_site=website
