go to your header.php (or whatever that theme calls the file responsible for everything north of content)
find:
<li><a href="http://jennas-internetmarketingcenter.com"></a>HOME</li>
replace with:
<li class="page_item page-item-2"><a href="http://jennas-internetmarketingcenter.com">HOME</a></li>
you closed a link '/a' before the end of the tag, and you didn't assign it the proper 'class'..
to add additional tags on that bar, copy and paste the line I rec'd as many times as you need a new link.. and then go to the code and change the text (home, ect) as well as the url... do these BEFORE the /ul /div tags.
this is the way to hard code it. if your using widgets or such to control them, this is going to confuse issues. I am not familiar with that theme so i don't know which method your using.
good luck!
