i have issue. as there is many places to put your CSS, sometime it is hard to locate it.
i hided menu in global CSS, after cornerstone and theme update cant find them. walked thru all pages, (it should be at global CSS) its not here. inspector tells that css is at ID=wp-custom-css
there should be option call all custom CSS writen in DB in one place. where in DB i can find that #wp-custom-css ?
