That is from missing phrases - I usually see it in relation to a modification where all the files haven't been uploaded or the mod isn't installed correctly.

For your smilies, try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

PHP Code:

define('DISABLE_HOOKS', true);
