the latest post ‘Screw the Taxman: 3 Legal Ways On How To Pay Less Taxes’ on the front page has a <div>
in its content (use the html tab of the editor to edit the post):
<h3>Everyone Wants To Pay Less In Taxes</h3>
<div>
<p>Everybod....
which gets broken by the excerpt function.
edit the post and remove that <div>
near the beginning and the corresponding </div>
after the main text, here:
...cash so you can <strong>pay less taxes</strong>.</p>
</div>
for some reasons there are lot of empty divs in that post’s content:
<div></div>
My sidebars are loading on the bottom of my home page sometimes
might be the same cause at other times.
if this is caused by the way the excerpt is generated, complain with the theme author.
