A service restart is required for the change to take effect.\n\n```bash\n# Edit the Apache configuration file, e.g., /etc/httpd/conf.modules.d/00-base.conf\n# Comment out the line:\n# LoadModule xml2enc_module modules/mod_xml2enc.so\n\n# Reload the httpd service\nsudo systemctl reload httpd\n```\n\n*Note: Disabling `mod_xml2enc` will cause any configurations relying heavily on `mod_proxy_html` or raw HTML/XML encoding conversions to function incorrectly or fail.
