);接下来在_files文件夹中创建一个文件夹名称为cache
在cache文件夹中创建三个文件夹名称如下
folders
images
menu
OK到这里已经完成的差不多了
我们返回服务器的现在你的服务器中应该是有这两个文件的如下
index.php和_files
如果对了我们在这个地方创建最后的文件夹名称如下
_uploads
如果想要后台上传文件的可以创建一个admin文件夹
admin后台源码下载地址如下点我下载
注意事项
1、PHP扩展安装：GD、mbstring、fileinfo、exif（不开启部分图片读取不到！！！！）
(宝塔默认已安装GD、mbstring扩展)
2、请务必保证根目录有
_uploads
文件夹，否则可能会报错！
3、如何修改上传密码、允许上传的类型？
打开 admin/index.php 文件，开头就可以看见
上面为魔改去广告版本
