最近，将网站运行的硬件进行了升级到了云服务器，同时用上最新的宝塔面板（基于centos7的7.4.7版本），php主要是用7.3版本，网上资料说，wordpress完美支持php7.0及以上版本，那么现阶段选择php7.3是可以承前启后的。
附为什么要选择php7，因为快；为什么选择php7.3，因为其稳定。
一通wordpress搬家操作。域名解析更换且成功后，浏览网站，出现这么一大串：

……好多好多，不忍描述。然后下面是网站正常的样子。
以上这些错误大概意思是“使用了未定义的常量gallerytag、videotag、taotag、filtersa、filtersb，这将在未来的PHP版本中引发错误“；
我去，不是说wordpress完美支持php7么？怎么会这样，细一思考，这其实不怪wordpress，而是用的是“知更鸟”主题，这个主题有很多字段模型，如上面的gallerytag、videotag等，这都是主题附带的。
那解决方法有两种：
一、升级主题，这个不太现实。
二、只是报了”Warning警告“，我能不能不让这些错误信息显示？
看来只需要关闭”PHP错误提示“就行了。宝塔面板中操作如下：
进入php管理，点“配置修改”，设置display_errors为关闭，然后保存，重启一下服务。
就这么简单。
如果不是在宝塔面板，那就要深入腹地，修改php.ini文件。
1、打开 php.ini
2、设置 error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
3、设置 display_errors = Off
其实两个方法，只是方式不同，改的都是同一个东西。
