I have a
div.notice.updated that is moving on the DOM and I can't locate the code that's doing that. Disabled all plugins and changed to a default theme without results.
I'm printing the element on the main content block and it jumps to the sidebar after the page finishes loading (it's clearly jQuery in action):
<div class="notice updated">Form sent</div>
I'm using Frank Bueltge's Admin Style plugin to get standard WP HTML code for the backend.
