Hi, I changed the website URL from http://www to URL without "www", using also 301 redirect in htaccess. Now, all the +1 Google which was for the name with www disaperred. It is not such a big deal, but anyway; is there a solution to get the +1s votes from the old address with www to the address without "www"?
How can you change URLs in G+? Are you talking about Google webmasters tools or +1 button? If you change your site URLs you can advice Google by visiting there webmasters tools > Configurations > settings. I think this can solve your problems.
