php - WordPress 中的数据库错误

Question

我正在使用 WordPress 创建一个网站。我仅在我的页面上收到以下错误，并且由于此错误而没有任何短代码在工作。此错误仅发生在 PAGES 上；他们在 POSTS 上工作正常。我该如何解决这个错误？

        OR wp_usermeta.meta_key = 'wp_capabilities'

        OR wp_usermeta.meta_key = 'wp_capabilities' 
        AND wp_usermeta.meta_value LIKE '%author%'

使用这个查询

SELECT wp_users.ID, wp_users.user_nicename FROM wp_users INNER JOIN wp_usermeta ON wp_users.ID = wp_usermeta.user_id WHERE wp_usermeta.meta_key = 'wp_capabilities' AND wp_usermeta.meta_value LIKE '%administrator%' OR wp_usermeta.meta_key = 'wp_capabilities' AND wp_usermeta.meta_value LIKE '%subscriber%' OR wp_usermeta.meta_key = 'wp_capabilities' AND wp_usermeta.meta_value LIKE '%author%' OR wp_usermeta.meta_key = 'wp_capabilities' AND wp_usermeta.meta_value LIKE '%editor%' OR wp_usermeta.meta_key = 'wp_capabilities' AND wp_usermeta.meta_value LIKE '%contributor%' ORDER BY wp_users.user_nicename LIMIT 0
