我有MediaWiki 1.28，PHP 7.1.1，php-fpm，nginx 1.10.3和arch linux。
Mediawiki称它与php 7兼容，但与PHP 7.1.1不完全兼容。但是，我相信的错误是PHP 5.3兼容性问题。我正在为我的mediawiki扩展获得PHP“预期成为参考”的警告。它们默认安装在MediaWiki 1.28安装中。
我不知道不兼容性会在多大程度上影响我的安装或适当的解决方案。
我得到一个nginx“上游标题太大”的错误导致某些页面的502响应：
当我登录并尝试访问某些网址时
/MediaWiki:Common.css或Index.php?title=Special:Search&search=Common.css&fulltext=Search&profile=all然后我收到502响应。如果我在退出时访问这些网址， 他们恢复正常200.我通过这篇文章的建议解决了它：upstream sent too big header while reading response header from upstream。
PHP兼容性问题是php-fpm缓冲区问题的原因吗？我应该降级到php 7还是可以修改扩展名？我的扩展程序是否可以更新，因为已经执行了此错误修复？
这是运行php文件的nginx块：
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_buffers 16 16k; # Added this fix
fastcgi_buffer_size 32k; # Added this fix
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_index /index.php;
}
还有一些日记：
