There are several ways to disable the display of the date or the author on the recording page.
Before starting any changes, I recommend backing up the data.
The first way:
In the page files, namely, the main page (index.php), the pages of individual entries (single.php), just the pages (page.php) you need to find and delete the parameters for the_author and the_time.
They look something like this (delete only them, not the whole line!):
<?php the_author (); ?>
<?php the_time('F jS, Y'); ?>
The second way:
Edit the _posted_on function in the functions.php file, which usually deletes data in brackets like “Published”, “Author”.
The third way:
Set a theme in the settings of which you can turn off the display date and author of the entry.
Fourth way:
Install a plugin that will disable the display of the date and author of the entry.
