Prompt "You do not have permission to view this directory or page because the access control list (ACL) is configured for this resource on the web server"

Most of the problems occur because the permissions problem solution is online. I only say that I have encountered problems here

Figure

Afternoon colleagues told me The company website could not access the record and found that the system directory permissions were set to log in today. First of all, it is definitely not the problem of iis. The website directory permissions are correct. I found that the company's four websites can be opened. The two websites that can't be opened for the asp script are PHP scripts. The problem is obviously obvious. The website cannot call the php program. Go to the php installation directory to set the permissions attribute - safely add user read permission Oh, the problem is solved.
