Hi,

If you would like to share a post to Social Network, there is a Social Share button on the stream. As long as the stream's privacy is set to public, guests will be able to see the Social Share button.

Do they also see the content, when I share something in FB or on Twitter?

hello Tanja,

I am really sorry for the delay of this reply as it is a weekend for us here.
Yes, check my screenshot below. Hope this help.

But what needs to be done to allow this. When I share want to share something to FB or Twitter it just says: Please login and a logo picture pops up.

Hi,

Do you mean that when you click on the "Social Share" button on your site as a guest, a login window pops up? If so then please provide us your site's access and FTP access so that we can investigate this.

No, I mean, when I share something in Facebook there is no preview or picture of my shared content, just the information to login to our community and a preview of my logo. What do I need to setup to the privacy files to change that. I want to share content to people on FB even if they are not part of our community yet.

Hi,

Clicking on sharing shouldn't prompt the popup. Please provide us your site's access and FTP access so that we can investigate this.

And also please provide us the link to the stream that causes this issue.
