【问题描述】：
我将一个 Wordpress 网站从一个旧的托管服务提供商转移到另一个。为此，我执行了以下步骤：
- 我从旧提供商处下载 public_html 内容；
- 我从旧提供程序中导出了数据库内容；
- 我尝试使用 WordPress 自动导入，但不起作用（无法与旧提供商建立 FTP 连接）；
- 我在新的提供程序中安装了 Wordpress；
- 我将旧的 public_html 文件夹复制到新文件夹中；
- 我从之前的数据库导出中导入了所有旧表；
- 我更正了 wp-config.php 文件中的数据库连接（DB_NAME、DB_USER、DB_PASSWORD...）；
此时该网站似乎可以正常工作……但“联系表”却不行。事实上，在激活 WordPress 调试模式后，如果我从站点发送消息，我会在 debug.log 中收到此响应：

谁能帮帮我？
【问题讨论】：
-
看起来您可能缺少“revslider”插件。我会检查它是否已在您的新网站上安装和激活。
-
感谢您的回复。收到您的消息后，我检查了我的新 WordPress 管理面板中的插件，但它们似乎没问题。我也尝试更新它们，但问题仍然存在。
