How to debug background/auto update?

Your WP installation must not require FTP credentials on plugins or extensions install.

  1. Open wp-content/plugins/unyson/unyson.php and decrease the version

    Important: Decrease only the last digit (third).

    /**
     * ...
     * Version: 2.5.0
     * ...
     */
    
  2. Add in {theme}/functions.php

    add_filter( 'auto_update_plugin', '__return_true', 99999 );
    
  3. Open phpMyAdmin and delete wp_option named cron. You can run this SQL:

    DELETE FROM `wp_options` WHERE `option_name` LIKE 'cron'
    
  4. Open admin page (plugins page) and repeat:

    1. Refresh
    2. Wait 1 second until Unyson will auto-update.

If after 10 refresh nothing happens, run the steps 3. and 4. again.
