我已经安装background_image.xml在 vqmod xml 文件夹中以更改 opencart 中的背景图像。这个插件可以完美运行，但会在标题处发出通知。
Notice: Undefined variable: server in C:\wamp\www\opencart\vqmod\vqcache\vq2-catalog_controller_common_header.php on line 54
这是插件链接：
我也试过error_reporting(0)但没有结果。这是代码vqmod\vqcache\vq2-catalog_controller_common_header.php
