I replaced the the hero image file using “replace imave”, now the hero image row has completely disappeared.
I have cleared caching tried recreating the hero image with no luck. Tried different browsers etc.
The site is here: http://lifeskills-bristol.org.uk/ the hero image should be showing under the menu.
The path to the image that should be appearing is here: http://lifeskills-bristol.org.uk/wp-content/uploads/2017/08/banner-transparent-3.png
