We have a very annoying problem with our Unyson plugin. For some users, all extensions are uninstalled automatically on random intervals (#1, #2) and we have no idea why this happens. The only clue is that it can be caused by the WordPress automatic update. We released a fix to stop automatic updates for Unyson plugin but the problem persists #3.

Why we think it's caused by the WP auto updates:

  • Our extensions are located within plugin directory in wp-content/plugins/unyson/framework/extensions
  • Before plugin update, we move all extensions outside the plugin to a temporary directory
  • After plugin update finished, we move them back in plugin directory (so the user doesn't have to install them again)
  • We use these 2 actions for before/after plugin update

I am thinking that on backgroup/auto update, the first action is fired, but the second one not (so the extensions are not moved back in plugin directory, so they are uninstalled).

We need a way to start manually WP backgroud/auto update and to debug the code execution (add print_r() or make requests to http://requestb.in/ with debug info).

  • Sorry this comment isn't constructive for the actual issue, but I do believe that storing those extensions inside a plugin folder that is distributed via wordpress.org just isn't a proper approach. Why aren't the extenstions separate plugins?

  • To be easier to manage. Extensions have a predefined directory structure and can be nested any level.

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.
