WordPress.WP.I18n.NonSingularStringLiteralDomain
Non Singular String Literal Domain
A translation or text-domain pattern does not match WordPress internationalization expectations.
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.
