將ocmod擴展一一禁用，然后重繪 查找問題。

您可以清除存盤檔案夾中的快取并禁用它們，或者登錄到您的 MySQL 并手動將它們全部關閉。

似乎一個擴展程式給您帶來了問題。

我沒有檢查整個代碼，但你不能替換部分字串......

<operation>
            <search index="0"><![CDATA[$this->load->view('marketplace/modification']]></search>
            <add position="replace"><![CDATA[$this->load->view('extension/module/modification_manager/list']]></add>
        </operation>

要檢查代碼是否正確添加或替換為 xml，請查找修改后的檔案并檢查您的代碼。
