Div Makes Div's Below It Disappear

ok so basically as soon as I include this into my content

it stops all divs underneat

Solution 1:

your example shows <div id="midmid"><?php include_once ("videob/activate-or-view.php"); ?>

But do you close the div after including the php aswell?

<divid="midmid"><?phpinclude_once ("videob/activate-or-view.php"); ?></div>

The second problem might be that the included file has ?> php ending tag at the end. Sometimes including php files into another php files will be messed up if the included file has php ending tag.
