Generic prompt (your report adds the evidence)
Please fix this production issue in my app.
Issue SEO-018: Page declares more than one canonical URL
Site: https://your-app.example
First confirm the issue in the code or live config. If it is not present, say so and change nothing.
Task: Make the page output exactly one <link rel="canonical">: find which layout or SEO plugin adds the extra one(s) in the evidence and remove the duplicate.
Constraints: make the smallest change that fixes this, keep the current design and behaviour, never paste secret values into code or chat, and tell me which files you changed.
Done when: View the page source and confirm a single canonical link.
