date missing from posts

Hi all. I have already asked this question in the Pagelayer support forum but maybe I can also find help here? I accidentally deleted the date and time block from my website (in customizer-single posts). The date’s usually under title (i think?). I have searched high and low to find out how to fix this have tried everything to but to no avail: php, plugins, reading the theme docs. Wondering if there is a simple solution out there for my dumb mistake. Any help, as I wait for answers elsewhere, would be SO MUCH appreciated.
