I’m using elementor alongside generatepress. Recently post titles showing on the actual article have completely disappeared, I’ve checked post settings and the template is not using canvas nor are content titles disabled. On the elementor side of things titles are not hidden in page settings.
There is also no CSS that would indicate that titles should be hidden for posts.
Yeah it doesn’t look to be either the metabox settings or elements. In elements there is no layout created, in the metabox the only thing disabled is page header/featured image – which after turning off has changed nothing anyway.
