Collapsiblock doesn't work - Here's a Fix...

IN styles.css, CHANGE:

#leftsidebar .block, #rightsidebar .block {
  padding-top: 10px;
  padding-bottom: 15px;
  padding-left: 20px;
  padding-right: 10px;
}

TO:

#leftsidebar .block, #rightsidebar .block {
}

AND IN block.tpl.php, CHANGE:

<?php if ($block->subject): ?>
  <h3 class="sideh"><?php print $block->subject ?></h3>
<?php endif;?>

  <div class="sidec"><?php print $block->content ?></div>

TO:

<div id="block-<?php print $block->module .'-'. $block->delta; ?>" class="clear-block block block-<?php print $block->module ?>">
<?php if ($block->subject): ?>
  <h2 class="sideh"><?php print $block->subject ?></h2>
<?php endif;?>
  <div class="sidec content"><?php print $block->content ?></div>
</div>
