How to fix migration issue on WordPress plugin “Search Everything”


WP pulgin Search Everything has been recently updated from release 8.1.6 to 8.1.7. It seems that during the migration, something happened that caused the following error on WP sites that have this plugin activated:

Warning: call_user_func() expects parameter 1 to be a valid callback, function ‘se_migrate_8_1_6’ not found or invalid function name in /home/benmeir/public_html/wp-content/plugins/search-everything/config.php on line 98

In order to fix this problem, just follow the steps below:

  • Delete the plugin folder directly in your filesystem:
rm -r <WP_FOLDER>/wp-content/plugins/search-everything

(replace WP_FOLDER by your WP folder)

  • Install “Search Everthing” plugin again on WP Plugin page.

The plugin has just been updated to release 8.1.8, that fixes the migration issue. The changelog on developer’s page just reported the issue:



  • Fixed a migration/update issue


  • Compatibility with WordPress 4.7
  • Security update: resolve SQL injection vunerability related to WP 4.7
