Hello, I am getting these validator errors on my page

Element style not allowed as child of element div in this context. (Suppressing further errors from this subtree.)

From line 249, column 740; to line 249, column 762

div></div><style type="text/css">#sppb-

Contexts in which element style may be used:
Where metadata content is expected.
In a noscript element that is a child of a head element.
Content model for element div:
If the element is a child of a dl element: one or more dt elements followed by one or more dd elements, optionally intermixed with script-supporting elements.
If the element is not a child of a dl element: flow content.

I tried enabling production mode but nothing happened. I don't see why that part of html should be there anyway. Please advise?
