我开发了一个带有大型数据库的 joomla 网站，特别是 jos_users，它拥有大约 200 万用户。
当我尝试在 joomla 管理员（联系人组件）的后端创建新联系人时，出现以下错误
我有专用服务器，并告诉我主机提供商查看是否有从他们这边或我这边到 MYSQL 服务器的更改...
但他们说脚本需要优化或其他什么......下面是错误
Error Loading Modules
MySQL server has gone away
SQL：
SELECT m.* FROM jos_modules as m LEFT JOIN jos_modules_menu AS mm ON mm.moduleid = m.id WHERE m.published = 1 AND m.access <= 2 AND m.client_id = 1 ORDER BY m.position, m.ordering
错误：
