  2. Log in to WordPress.
  3. Go to Sucuri Security > Settings.
  4. Click on the Hardening tab.
  5. Find the section labled Plugin and Theme Editor.
  6. If the section is red, click on the Apply Hardening button.

You have now prevented your WordPress plugin and theme files from being edited as easily by malicious code.
