plugin_header_invalid_license
plugin header invalid license
The plugin's license metadata is missing, invalid, or inconsistent.
Why It Shows Up
Plugin Check found license information that does not match WordPress.org expectations across the plugin header, readme, or bundled files.
Why It Matters
Clear license metadata helps users and repository reviewers understand whether the plugin can be distributed and modified.
How to Fix
- Declare the license in the plugin header and readme.
- Use a valid SPDX-style license name or a WordPress.org-accepted GPL-compatible license.
- Keep bundled third-party library licenses intact and compatible.
