Div Error with Lists

Is it the text starting “Church mailing lists” ?

Suggest that you install and use firebug.
I think you need “clear:left;” coded into the div which encloses the misplaced content.

I actually already have firebug installed and have a <div class=”clear-line”> implemented.

When I do this in Firebug it corrects but the code is currently implemented and the page is still rendering incorrectly.

I have also cleared the cache multiple times.

Do you know of anything else it could be?

Maybe check for unclosed elements https://validator.w3.org/check?uri=http%3A%2F%2Fwww.accurateleads.com%2Fchurch-mailing-lists%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

Yes you have a
<div class="clear-line"></div>

BUT there is NO CSS code that actually does this.
In this case it is not the thought that counts !
In all likelyhood this has been lost in various theme edits.

When I add this rule in firefox:
.clear-line { clear: both; }
It all comes good.

Then you should lookinto what is going wrong with your form on the right hand side.
