Let's say you have a second blog, and you want to share the same blog post on your second blog automatically. After adding the blog, what you share in your blog will be auto-sync to the second blog. And you can add as many blogs as you want.
To do this, please follow the steps below:
1. Go to FS Poster > Accounts > WordPress menu;
2. Copy your site URL from the browser search box and enter the site URL, username, and password;
3. Click the ADD A SITE button.
If you are using a sharing hosting, you need to use HTTPS because the XML-RPC protocol is commonly exploited/abused. Due to that reason, HTTP outbound requests are blocked to XMLRPC.
