Cannot get rid of small vertical line…

I have searched but have not found anything here re. this problem – I get this little vertical line at the end of every single page (except my posts/home page). It′s also there when I look in the source code:

</div> <!– end of storycontent –>
<div class=”postcleardiv”></div>
</div> <!– end of postcontent –>
| <div class=”pagenextback”>
</div>
</div>

See the vertical line symbol before the pagenextback div? After updating each page from the Dashboard in WordPress, this code gets inserted automatically I think, and I can′t figure out where and how to get rid of it…

I know my code is bad, but this is only a personal site, so forgive me – but if anyone can help, it′s https://www.themadcatlady.com – go to, for example, the Photo Gallery page, and you will see the little line right there under the gallery listings on the left.

Any help would be appreciated, thanks. ??
