Some important notices before updating:
We recommend you have a current backup of your site including wp-content folder, wp-config.php file and .htaccess file and a copy of WordPress database. If you don’t know how to take action, you can use several plugins such as UpDraft Plus and WordPress Backup Buddy. Moreover, you should backup ThemeMove’s theme options in Dashboard >> Appearance >> Customize.
This is the customizer’s screen
