Live Generation Test
Ran a dry-run against: New_Template.pdf
Exit code: 127 | PDF produced: ✕ No

Quick Fix Guide
Common causes and fixes for "Certificate file was not produced":
| Symptom | Fix |
|---|---|
| pypdf not found | pip install pypdf --break-system-packages |
| exec() disabled | Remove exec from php.ini disable_functions, then restart PHP-FPM |
| issued/ not writable | chmod 755 issued/ && chown www-data:www-data issued/ |
| Template has no placeholders | Template must contain {{PLACEHOLDER}} tokens — generate_cert.py rejects plain PDFs |
| python3 not in PATH | which python3 — install python3 package or set full path in generateWithPython() |
