Troubleshoot Signature Fields

Checklist

1. Confirm the official Signature Add-On is installed and active.
2. Confirm the form contains the Signature field and has been saved.
3. Test in a supported browser on a desktop and touchscreen device.
4. Submit a test signature and inspect the saved entry.
5. If the signature image is not generated, ask the administrator to verify PHP GD support and server error logs.
6. If the signature saves but does not display in a CHKM8 page, test the underlying entry separately to distinguish capture from display issues.

Do not delete the original record to troubleshoot

Use a dedicated test form or test entry where possible. Keep production records intact while diagnosing rendering problems.
