I seem to have a very large grey area under my header and before the page content starts. It looks unprofessional. I am using WP Bakery builder (not as good as Unyson!) and I cannot see anywhere to get rid of it.

Please help.

My home page seems to be okay. But subsequent pages are not and some of them are built using a template created from the home page.

the website is: http://www.rhisotope.org
