WordPress database error: [Query execution was interrupted]
SELECT t.*, tt.* FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON t.term_id = tt.term_id WHERE tt.taxonomy IN ('nav_menu') ORDER BY t.name ASC
This means that we lost contact with the database server at
localhost. This could mean your host’s database server is down.
If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.
