I get the error:

Fatal error: Call to undefined function is_site_admin() in /home/*****/domains/****.**/public_html/wp-content/plugins/buddypress-like/bp-like.php on line 248

(I replaced some lines with stars myself. Didn’t wanna publish.)

Think I solved it by adding the line
<?php echo get_avatar( get_the_author_email(), '40' ); ?>
to the index.php

Now all I have to figure out is how to Tango Smileys Extended work too, without every smiley getting a huge frame. xD
