我最近注意到，当我尝试加载外观＆gt;自定义我收到此错误：
Notice: Trying to get property of non-object in /home/kavwxoln/feelfreehypnosis.com/wp-includes/class-wp-customize-nav-menus.php on line 682

我在Google上搜索了thread，但是在应用那里提供的答案时
ALTER TABLE `wp_terms`
CHANGE COLUMN `term_id` `term_id` BIGINT(20) UNSIGNED NOT NULL
AUTO_INCREMENT FIRST,
ADD PRIMARY KEY (`term_id`),
ADD INDEX `name` (`name`),
ADD INDEX `slug` (`slug`);
我从phpmyadmin得到了这个答案：
#1068 - Multiple primary key defined
所以我正在寻找asnwer如何解决这个问题。
答案 0 :(得分：0)
这就是我的所作所为：
转到SQL编辑器并粘贴此代码：
CREATE TABLE wp_terms（
term_id bigint（20）unsigned NOT NULL AUTO_INCREMENT，
name varchar（200）NOT NULL DEFAULT''，
slug varchar（200）NOT NULL DEFAULT''，
term_group bigint（10）NOT NULL DEFAULT'0'，
PRIMARY KEY（term_id），
独特的钥匙slug（slug），
KEY name（name）
）ENGINE = MyISAM AUTO_INCREMENT = 603 DEFAULT CHARSET = utf8;
从.sql文件打开以前保存的备份，然后使用phpmyadmin通过SQL编辑器插入。
问题解决了！
注意：只从备份中获取行，而不是整个数据库！
