Google Analytics web property: link has been removed from http://swebdizajn.com November 29, 2011
Your Webmaster Tools http://swebdizajn.com site is no longer linked to a Google Analytics web property. Possible reasons are:
You are no longer the owner of the site in Google Analytics, and nobody else owns both the site and the property
Another site owner removed the link.
After that I restored to backup and then accepted the Google message to tell them that all is well. How long will I have to wait for my site to return to the position where I was?
