Hi,
I have the same issue with an up-to-date WordPress (3.9.1) and Multisite Language Switcher plugin (0.9.9.3).

Has the fix been released yet in theory?

Cheers

I used https://delete.twitlan.com/index.php to delete all tweets.

This plugin needs PHP5…

In includes/wp-facebookconnect/fbconnect.php

// The following line causes an error in the PHP admin console if
  // you are using php4.
  try { // ATTENTION: This plugin is not compatible with PHP4
    $api_client->feed_getRegisteredTemplateBundles();
    $success = true;
  } catch(Exception $e) {
    $success = false;
    $error = $e->getMessage();
  }

Your error is due to the use of the object facebook by referencing methods etc by a ->
