我安装了这个插件https://wordpress.org/plugins/wp-gallery-custom-links/并在安装过程中遇到错误,我在页面刷新之前没有时间阅读.

现在我的媒体选择器根本没有加载.

我没有运气完全删除了插件,现在我甚至无法再访问wp-admin了.得到如下错误：

我已经下载了wordpress的新副本并替换了wp-admin文件夹,wp-includes文件夹,wp-config.php文件,wp-login.php文件.

我已经尝试更改插件文件夹上的名称,仍然无法正常工作,我已尝试删除我的主题,以便能够到达wp-admin,但仍然无法正常工作.

我怀疑它可能是数据库,但我很幸运找到问题..任何人都可以帮忙吗？

解决方法:

我已经多次遇到过这个问题,正如Vaviloff所说,一个空间放在文件的开头(在<？php之前)就是你要找的东西. 一些可能的原因：
>一个损坏的插件
>一个腐败的主题
>你的Wordpress安装中的入侵(你会在文件的开头看到一些eval())

可能的解决方案 ：

>查看相关文件：/var/www/vhosts/xxxx.com/httpdocs/wp-content/themes/caroli/functions.php:1
并删除<？php之前的空格
>禁用您安装的最新插件,看它是否有效
>运行像Wordfence这样的插件(以防万一),它会扫描你的文件
比手动更快,检查与WP核心的差异或查找可疑代码(免费版本可以完成所有这些)

编辑：
我刚看到你无法联系到wp-admin.这很棘手,但有时候我遇到了同样的问题.好吧,这是一个入侵(由于一个过时的插件).

我做了什么？

>我主题的备份
>我的数据库的备份
>我上传的备份
>已安装插件的列表
>更改了所有密码
>删除了服务器的所有相关部分(所有备份后)
>重新安装新的WP
>恢复主题/数据库/上传/插件(安装插件时检查插件的最新更新)
>安装Wordfence,以防万一
