Nginx ERR_TOO_MANY_REDIRECTS 通過調整 WordPress 永久連結 |301 錯誤 Ubuntu 18.04

• 作業系統：Ubuntu 18.04.5 LTS（擁有我自己的 VPS）
• 網路伺服器：Nginx/1.18.0
• MySQL: mysql Ver 8.0.22 for Linux on x86_64 (MySQL Community Server - GPL)
• WordPress：5.6

當我將 WordPress 中的永久連結選項（ScreenShot: /wp-admin/options-permalink.php）從預設值（?p=123）更改為*/%postname%/（頁面上的最後一個選項）時，我收到以下錯誤：“ERR_TOO_MANY_REDIRECTS”，狀態碼為301* ，僅適用於首頁 （直接使用 example.com），所有其他頁面都執行良好，即使是新的永久連結選項也可以正常工作，因此預設部落格可以通過以下方式訪問：*/hello-world/*直接。

知道為什麼嗎？這是我的伺服器完成後要做的最後一件事，在這個小錯誤上花費的時間比其他所有事情都多，哈哈。注意：我已經禁用了所有外掛，除了用於清除伺服器端記憶體的 nginx 記憶體。我也匿名訪問網站。

我遵循了本教程：SpinUp WP（我做了所有事情，包括 CH6）。特此我的 NGINX 設置：

NGINX 配置文件（出於隱私原因，我已將使用者名更改為 omar）：

如果我需要展示更多的東西，請告訴我，我會展示更多。

Alhamdulillah，我找到了答案。這完全是由於試圖成為完美主義的穆斯林，我在裡面的 URL 中有大寫字母：/wp-admin/options-general.php。所有對上帝的讚美（Alhamdulillah），通過將所有字母變為小寫來解決。憑藉上帝的旨意（真主），它將幫助您的兄弟和非兄弟。
