WordPress.WP.I18n.NonSingularStringLiteralDomain

Non Singular String Literal Domain

A translation or text-domain pattern does not match WordPress internationalization expectations.

low weight

Why It Shows Up

Plugin Check found missing text domains, mismatched domains, missing translator comments, variable-only strings, placeholder issues, or deprecated translation loading patterns.

Why It Matters

Translation issues make the plugin harder to localize and can break strings for non-English WordPress users.

How to Fix

  • Use the plugin slug as the text domain unless the plugin intentionally declares a different one.
  • Keep translatable strings literal and move variables into placeholders.
  • Add translator comments before strings with placeholders or ambiguous context.
