The helpline javascript still points to the old var.

Open: template/posting_buttons.html

Find:
<input type="button" class="btnbbcode" accesskey="y" name="addlistitem" value="[*]" style="width: 40px" onclick="bbstyle(-1)" onmouseover="helpline('e')" onmouseout="helpline('tip')" />

Replace With:
<input type="button" class="btnbbcode" accesskey="y" name="addlistitem" value="[*]" style="width: 40px" onclick="bbstyle(-1)" onmouseover="helpline('y')" onmouseout="helpline('tip')" />
