If you are using mobstac to power the mobile version of your Blogger blog, you will have to add the mobstac redirection code in the head section of your blog’s html before your blog can be redirecting automatically to your mobstac site when viewed on mobile devices.
Check the redirection code you added to your blog html and ensure there is “http://” before your mobstac url in the code and not just yoursite.mobstac.com.
