🛠️ WordPress Hardening
The plugin helps tighten your WordPress configuration by addressing common weak points:
✔ Prevent code execution in the uploads folder
✔ Block login feedback (hides user errors to thwart enumeration)
✔ Disable XML-RPC (often abused by bots)
✔ Turn off directory browsing
✔ Restrict usernames (e.g., block the default “admin”)
✔ Other hardening tweaks that improve baseline security without user effort
