Hardening File Permissions on WordPress Installations

Incorrect file permissions can create both security issues and failed updates. Permissions should support the application without giving unnecessary write access.

Guiding Principles

• Restrict write access to only what the application genuinely needs.
• Review ownership after migrations or manual file uploads.
• Avoid temporary permissive settings becoming permanent.
• Pair permission review with plugin and theme hygiene.

Support Note

If an update fails after permissions are tightened, identify the specific path or process that needs adjustment instead of broadening permissions across the entire installation.
