解決 WordPress 出現錯誤訊息「伺服器傳回未預期的回應。檔案可能已完成上傳，請查看媒體庫或重新載入頁面。」或「Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page」

1. 修改 php.ini 的 upload_max_filesize
2. Nginx 伺服器：加入這行到 php.ini  （自行更改檔案大小）client_max_body_size <span class="hljs-number">10</span>M;
3. 如果以上方法都沒用，可以直接安裝 Big File Uploads – Increase Maximum File Upload Size ，立刻解決。
