I have updated the version of wordpress, and my webpage has not been working all of a sudden. I have debugged to see what the problem is, and I could not understand any of the explanation that is written. I have spent hours trying figure out what it meant, and still could not grasp what I have to change and add. Could someone please explain what it means, and what I must do in order to fix this? Is there an instruction written in the notice & error? I am sorry if I did not provide enough information, I am very new to coding and web page making :(

Seems like the update went wrong and some files got corrupted.

You can try this to fix it:

  1. Download a new Wordpress installation zip https://wordpress.org/download/

  2. Remove the folders wp-admin & wp-includes from your server

  3. Reupload those folders from the fresh downloaded Wordpress zip

Note: this does not delete your site content, the content of your website is in the database and in the wp-content folder.

Your wordpress version 5.3 need php 7.4 version to be runned properly

so you need to upgrade your php version

or downgrade you wordpress version to 5.2 and disable wordpress auto update 

// wp-configs.php    
define( 'WP_AUTO_UPDATE_CORE', false );
