Currently my web site is in staging i.e., working as IP address http://example.com. I have added google share button to share web pages in g+. When I try to share a link like this http://example.com/index/ It shows error like "There was a problem saving your post. Please try again." Can I share IP address in g+.
Please help. --
In order for the share button to work, the page in question must be publicly accessible. The Google share bot needs to be able to get to your page to get the information that will be shared. So as long as the machine is public, and can be reached using either the host name or IP address you specify in the share link, this should work.
If it doesn't, you may want to post more context to the page showing exactly how you're doing the share.
Add a real domain to url option... That solve my problem!!!
