And HTML is turned on individually,
Admin.php calls HTML. Both are not in the same directory,
When the HTML post is found that its own directory becomes the directory of admin.php, which shows that the file that accepts post does not exist,

Because your admin_login.html is encoded, so there is garbled.

As for the submission, 404 of the action that should be your form is not written to the path.

Because your admin_login.html is GBK code, so there is garbled.

You need to check and modify the action of a form, post your code to see

1, you did not tell what kind of garbled
2, #2 in the URL is obviously more than the first level of admin
3, do not see the smarty requirements of the working directory settings
4. Why is the template file not in the working directory required by Smarty?
