No p element in scope but a p end tag seen

Hi everybody,
I always try and validate my site, but now I have one last problem. There seems to be a stray p somewhere, because I get this error “No p element in scope but a p end tag seen”.
It is only on my homepage, so it isn’t in the widgets I think. But I can’t seem to find where it is from, from what file.
Can somebody shed some light on this?
Thanks.

Johanna
