为站点备份SQL数据库，并尝试通过php myadmin在数据库上手动运行这些查询。更改URL以匹配您的站点http://example.com/blog

像往常一样，在数据库上运行查询时要小心

 UPDATE wp_options SET option_value = replace(option_value, \'http://www.oldurl\', \'http://www.newurl\') WHERE option_name = \'home\' OR option_name = \'siteurl\';

 UPDATE wp_posts SET guid = replace(guid, \'http://www.oldurl\',\'http://www.newurl\');

 UPDATE wp_posts SET post_content = replace(post_content, \'http://www.oldurl\', \'http://www.newurl\');

 UPDATE wp_postmeta SET meta_value = replace(meta_value,\'http://www.oldurl\',\'http://www.newurl\');
