Header of wordpress static pages do not render correctly

Question

I use WordPress on a website and the header of two static pages is not the same and I do not understand why.

• Good behavior : http://gvallver.perso.univ-pau.fr/?page_id=511
• wrong behavior : http://gvallver.perso.univ-pau.fr/ (and other pages)

Here is a screenshot, on the left the wrong behavior, on the right the good behavior :

I obtained the same rendering on Google Chrome and Firefox.

Answer 1

I assume you refer to the "Heading" of the page.

It looks like it's caused the ResearcherID badge that you added.

It references a CSS file at http://labs.researcherid.com/static/mashlet/css/mashlet.css which changes how the Heading is displayed.

I believe if you enter the "text" editor (rather than the visual editor), you should be able to quickly fix it.
