The Social Sidebar extension adds links to a Twitter and Facebook account in the sidebar.


  • Copy the code into a file and place the file(s) in a directory called SocialSidebar in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    require_once "$IP/extensions/SocialSidebar/SocialSidebar.php";
    // Specifiy the Twitter and Facebook pages:
    $wgFacebook = "The complete link to your Facebook page";
    // e.g. $wgFacebook = "https://www.facebook.com/pages/Mount-Wiki/94013348117";
    $wgTwitter = "The name of your Twitter account";
    // e.g. $wgTwitter = "MountWiki";
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Note Note:

  • The description (label) of the portlet should be set in [[MediaWiki:Socialsidebar]].
  • When used in combination with another plugin that adds boxes to the sidebar, the order of calling the extension in the LocalSettings.php will determine the order of the extension boxes in the sidebar.
  • Because of inconsistencies in the skin implementation, this extension will work with the following skins: cologneblue, standard, nostalgia
