Fix "[ACL] Access to context [/image/] is denied"

This guide explains why a web server shows this message in its log, and how to fix it.

Dedicated Servers2 min read9 steps

Note: This guide needs root access to the server. It is for VPS and dedicated server owners. It applies to the LiteSpeed web server.

What does the message mean?

A web server is the program that sends web pages to visitors. LiteSpeed is one kind. A context is a rule for one folder or web address, such as /image/. An ACL, or access control list, is a list that says who may enter and who may not.

So the message means a visitor was refused. The visitor's address was not allowed by the ACL on the /image/ context. You see it in the error log. Visitors may see a "403 Forbidden" page.

Warning: Do not simply open access to everyone. Find out who should be allowed. Take a backup of any file before you change it.

Common causes

  • A context has an "Accessible" list that does not include the visitor's IP address. An IP address is the number that names a computer on the internet.
  • A "Denied" list blocks the address. Maybe a security tool added it.
  • An old .htaccess file has Deny from all or Require all denied lines.
  • Hotlink protection is blocking images used from other sites.

Steps to fix it

  1. Find the real error. Read the LiteSpeed error log.
tail -n 50 /usr/local/lsws/logs/error.log

This shows the last 50 lines of the log. Look for the IP address that was blocked.

  1. Log in to the LiteSpeed WebAdmin Console. Its address and login come from your server setup.
  2. Go to Virtual Hosts and pick your site.
  3. Open the Context tab and click the /image/ context.
  4. Look at the Access Control section. Check the Allowed List and Denied List.
  5. Add the right address to the allowed list, or remove it from the denied list. Use ALL only if the images should be public.
  6. Save, then do a Graceful Restart.
  1. Check for an .htaccess file in the image folder.
cat /home/user/public_html/image/.htaccess

This prints the file so you can read it. Remove or fix any lines that deny access.

  1. Check file permissions. Folders should be 755 and files 644.
Tip: If a firewall or security plugin is the cause, add the visitor to its allow list. If you are unsure, open a support ticket.

Quick recap

  • The message means the ACL of the /image/ context refused a visitor.
  • Read the error log to see which address was blocked.
  • Fix the allowed and denied lists in WebAdmin, then restart gracefully.
  • Check .htaccess and file permissions.
