Wordpress adding in anchor elements when I save a page in html editor

Question

This page I am editing in the html editor. I pasted in my list from my text editor. You'll notice that the second last list item is all a link, thats because wordpress has taken it upon itself to wrap the whole thing in an empty tag! Why is it doing this and more importantly, how do I stop it?

FYI here is the relevant ul

<ul class="company-details">
        <li>Target Health & Fitness</li>
        <li>7 Sheffield Road Holmfirth HD9 7BW</li>
        <li>01484 681000</li>           
        <li><a href="mailto:enquiry@target-leisure.com">enquiry@target-leisure.com</a></li>
    </ul>

inside that wordpress has added an anchor, if you inspect it using inspector or firebug.

I've added these filters thinking they'd work but they haven't

remove_filter( 'the_content', 'wpautop' ); 
remove_filter( 'the_excerpt', 'wpautop' );

Answer 1

I don't remember which one, but there is probably a conflict with tone of your plugins. I had the same issue in the past.

Deactivate all of you plugins, then go through and reactivate them one by one.
