Links to social media icon doesn't work

Hi, I'm not sure I did it the right way but I have enabled the social media icons as described in the instructions. I chose to have: Facebook (https://www.facebook.com/eric.thoren.35) Twitter (https://twitter.com/ericthoren) Mail (info@ericthoren.se) Website (www.ericthoren.se) Phone (0046705606465) I have entered the correct addresses as above per type, but only the website icon works in the sense that clicking on it gets me to the home page of the website. Clicking on any other icons doesn't do anything. What did I do wrong? You can check on: www.ericthoren.se/posts Best regards, Eric
