CPU Usage Reaching 100% Limit

Dear @farhadvn I looked into the root directory of public_html but there is no user.ini or php.in file. Even changed setting to show hidden files.

I have added the cron job with cpanel and disabled the cron in config as you suggested.

This is how my config file looks like.

<?php
/** Enable W3 Total Cache */
define('WP_CACHE', true); // Added by W3 Total Cache

 
/**

 *
 * The wp-config.php creation script uses this file during the

 *
 * This file contains the following configurations:
 *
 * * MySQL settings
 * * Secret keys
 * * Database table prefix
 * * ABSPATH
 *
 * @link https://codex.wordpress.org/Editing_wp-config.php

// ** MySQL settings - You can get this info from your web host ** //

Thanks @farhadvn i will do as you instructed. Meanwhile could you please tell me what should be acceptable CPU usage limit? As I can check on cpanel, I am consistently hitting over 50% of CPU limit several times a day. Most of these times, I am not even accessing the Admin area. In fact I just noticed that I hit 100% usage briefly but I wasn’t accessing the website.
