There are several places that cannot be done by following the steps.
For example, in the background of the previous section, it is correct to change static to __STATIC__/static, but there is a wrong file in the JS of the background template. It should be h-ui.admin login.js and the result is login. Inside the html is h-ui login.js.
Can you provide a copy of the code corresponding to the course?
The source code should be available in the QQ group
