最近发现论坛有人反应QQ互联插件乱码，出于以往的经验，是由于安装时与站点编码不一致导致。
关键现在安装的时候会自动选择与站点编码一致的xml文件安装，实在搞不懂为啥还会出现这类问题，焦虑了，有问题的站长不妨把你的安装过程详细写下来，方便我们排查是否是bug。

由于QQ互联是系统插件，是无法卸载和重新安装的，必须要通过数据库操作才能解决此类问题。

解决方法：

第一种方法：

1.根据您网站的编码，选择执行下面对应的sql（需要在数据库里执行）。
简体GBK编码的站点：

UPDATE pre_common_plugin SET modules = 'a:6:{i:0;a:10:{s:4:"name";s:7:"connect";s:4:"menu";s:0:"";s:3:"url";s:0:"";s:4:"type";s:2:"11";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"0";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:1;a:10:{s:4:"name";s:7:"spacecp";s:4:"menu";s:6:"QQ绑定";s:3:"url";s:0:"";s:4:"type";s:1:"7";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"1";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:2;a:10:{s:4:"name";s:6:"qqshow";s:4:"menu";s:4:"QQ秀";s:3:"url";s:0:"";s:4:"type";s:1:"7";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"2";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:3;a:10:{s:4:"name";s:7:"connect";s:4:"menu";s:0:"";s:3:"url";s:0:"";s:4:"type";s:2:"28";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"0";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}s:6:"system";i:2;s:5:"extra";a:2:{s:11:"installtype";s:6:"SC_GBK";s:10:"langexists";i:1;}}' WHERE name = 'QQ互联';

简体UFT-8编码的站点：

UPDATE pre_common_plugin SET modules = 'a:6:{i:0;a:10:{s:4:"name";s:7:"connect";s:4:"menu";s:0:"";s:3:"url";s:0:"";s:4:"type";s:2:"11";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"0";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:1;a:10:{s:4:"name";s:7:"spacecp";s:4:"menu";s:6:"QQ绑定";s:3:"url";s:0:"";s:4:"type";s:1:"7";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"1";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:2;a:10:{s:4:"name";s:6:"qqshow";s:4:"menu";s:4:"QQ秀";s:3:"url";s:0:"";s:4:"type";s:1:"7";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"2";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:3;a:10:{s:4:"name";s:7:"connect";s:4:"menu";s:0:"";s:3:"url";s:0:"";s:4:"type";s:2:"28";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"0";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}s:6:"system";i:2;s:5:"extra";a:2:{s:11:"installtype";s:7:"SC_UTF8";s:10:"langexists";i:1;}}' WHERE name = 'QQ互联';

2.执行完上述sql后，进入站点后台-》工具下，点击更新缓存。

第二种方法：

如果第一种方法执行后不起效，您进入您网站目录/source/plugin/qqconnect目录下，检查是否存在discuz_plugin_qqconnect.xml文件。
如果存在，则可以按下面的方法再试下。
不需要区分网站编码，执行下面的sql：

UPDATE pre_common_plugin SET modules = 'a:6:{i:0;a:10:{s:4:"name";s:7:"connect";s:4:"menu";s:0:"";s:3:"url";s:0:"";s:4:"type";s:2:"11";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"0";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:1;a:10:{s:4:"name";s:7:"spacecp";s:4:"menu";s:6:"QQ绑定";s:3:"url";s:0:"";s:4:"type";s:1:"7";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"1";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:2;a:10:{s:4:"name";s:6:"qqshow";s:4:"menu";s:4:"QQ秀";s:3:"url";s:0:"";s:4:"type";s:1:"7";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"2";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}i:3;a:10:{s:4:"name";s:7:"connect";s:4:"menu";s:0:"";s:3:"url";s:0:"";s:4:"type";s:2:"28";s:7:"adminid";s:1:"0";s:12:"displayorder";s:1:"0";s:8:"navtitle";s:0:"";s:7:"navicon";s:0:"";s:10:"navsubname";s:0:"";s:9:"navsuburl";s:0:"";}s:6:"system";i:2;s:5:"extra";a:2:{s:11:"installtype";s:0:"";s:10:"langexists";i:1;}}' WHERE name = 'QQ互联';

执行完后，进入站点后台-》工具下更新缓存。
