SEO Ultimate file editor code problem?

Hi,
My site is https://daisyleebeacon.com

I have installed SEO Ultimate Plugin on my site. I pretty quickly started getting 404 errors. The error seems to be telling me that the google bot has found a broken link to a calendar. Since I didn’t have a calendar on the site I couldn’t figure out why. I finally added a calendar from the widget hoping that would stop it, but it didn’t.

Now in following the details of the training video on SEO Ultimate, at the page where it is showing the File Editor, I noticed that the code that is in my .htaccess box is very different from the code in the training video. Mine has a bunch of stuff that is not right.

When I first opened my site at Bluehost, I tried using a site builder called livesite instead of word press. I shortly realized what a mistake that was and removed it. But I remember it had a calendar and staff pages. Then I installed WP.

What I am seeing in that File Editor Box on my site now, are a bunch of re-directs that have the words livesite in the coding.

I really know nothing about coding, so am very nervous of changing that because of the warning on the SEO Ultimate training that it requires code knowledge to make changes in that box or I could lose my site.
The coding that Ultimate training has in their box is very simple:

#begin wordpress

#end wordpress
#test

What should be in my box to make it work right?
