Fixing Webalizer Errors: Unable to Lock DNS Cache File

Introduction:
If you encounter the Webalizer errors:
Error: Unable to lock DNS cache file /usr/local/psa/var/webalizer.cache
don’t worry this is a common issue caused by cache file permissions. You can quickly resolve it by recreating the cache file and correcting its ownership and permissions.

Steps to Fix Webalizer Errors

1. Remove the existing cache file

rm -f /usr/local/psa/var/webalizer.cache

2. Create a new empty cache file

touch /usr/local/psa/var/webalizer.cache

3. Set the correct ownership

chown root:root /usr/local/psa/var/webalizer.cache

4. Set proper file permissions

chmod 644 /usr/local/psa/var/webalizer.cache

5. Verify file status

stat /usr/local/psa/var/webalizer.cache

Pro Tip

Always make sure you’re logged in as root before making changes. Incorrect ownership or permissions can prevent Webalizer from functioning correctly.
