After restoring a WordPress website which was using Divi theme, you might have faced the below error.

Fatal error: Uncaught Error: Class 'ET_Core_Cache_Directory' not found in /home/*******/public_html/wp-content/themes/Divi/core/components/init.php:9

This happens due to missing files under the location

/wp-content/themes/Divi/core/components/cache

Directory.php

File.php

init.php

In such situations, you will have to change the MySQL’s tmpdir.

1. Create the new temp directory

mkdir /var/lib/mysql/tmp
chmod 1777 /var/lib/mysql/tmp

2. Make the new folder as the tmpdir by adding the below to server’s /etc/my.cnf

tmpdir = /var/lib/mysql/tmp

3. Restart mysql

service mysqld restart
