Can anyone tell me what this means:
Following the announcement of Google+ API deprecation scheduled for March 2019, a number of changes will be made to Blogger’s Google+ integration on 4 February 2019.
Google+ widgets: Support for the “+1 Button”, “Google+ Followers” and “Google+ Badge” widgets in Layout will no longer be available. All instances of these widgets will be removed from your blog.
+1 buttons: The +1/G+ buttons and Google+ share links below blog posts and in the navigation bar will be removed.
Please note that if you have a custom template that includes Google+ features, you may need to update your template. Please contact your template supplier for advice.
Google+ Comments: Support for Google+ comments will be turned down, and all blogs using Google+ comments will be reverted back to using Blogger comments. Unfortunately, comments posted as Google+ comments cannot be migrated to Blogger and will no longer appear on your blog.
It popped up when I clicked on my blog.
