If you disable all the plugins and there is still a problem it’s not the theme’s fault. You must have modified a file or an option and I really don’t know where to start.

Did you change anything in the theme’s files?

Unfortunately not. It will break the design.

Did you create the child theme (as the above tutorial says) and activate it?

Hi! That will happen every time you update the theme, it overwrites style.css.

You need to create a child theme and all your changes remain intact. It’s actually recommended (with all themes in general) if you look in style.css, at the top.

Maybe something like:

/*  Remove Hentry
/* ------------------------------------ */
function remove_hentry( $classes ) {
	if( !is_single() ) {
		$classes = array_diff($classes, array('hentry'));
		return $classes;
	} else {
		return $classes;
	}
}
add_filter( 'post_class', 'remove_hentry' );

You made me curious.. Try adding this in functions.php

/*  Remove Hentry
/* ------------------------------------ */
function remove_hentry( $classes ) {
	$classes = array_diff($classes, array('hentry'));	

	return $classes;
}
add_filter( 'post_class', 'remove_hentry' );

I don’t know what to say, it appears on my end. There is an image with a calculator and some other stuff laying on a table.
