I have a site where visitors can search in a gallery of products, every day I update the status of the products available.
Is there a way that when I'm (role = Admin) updating the database, for all visitors logging in to the page or currently on the page, a page (box?, lightbox?) opens with some text info on 'Whe are currently updating the data' or something like that?
I've tried to do this with a box or lightbox, but it only appears in my window. If somebody else on another computer visits the site, they can still see the whole content.
