YES! thanks a lot, this solved it 🙂
Have you tried changing the theme? When I change theme the ugly banner dissapears BUT that means I have to build the whole site once again on a different theme – which is quite stupid 🙂
Yes, I haven’t got anything useful from them. They suggested that it may be the problem with one of the plugins but it isn’t.
Is it maybe possible that the theme I’m using has something to do with LiteSpeed server? The theme is Avada.
