Troubleshoot a missing Letter Manager menu
Restore activation, file loading or session access without changing unrelated modules. The guide then takes you through the correct route, the checks to complete before making changes, the workflow in order, and the evidence to review afterwards.
Where to goAdmin Area → Setup → Modules; server → modules/letter_manager
Before you start
- Use an authorised account and confirm the customer, external recipient, template, letter or configuration is the intended one.
- Follow the exact route shown above and verify the stored record, generated file and delivery evidence instead of relying on an alert alone.
What you’ll accomplish
Restore activation, file loading or session access without changing unrelated modules. These instructions follow the inspected module’s live hook, route, controller, model, installer, PDF helper and view flow.
Follow these steps
- Verify Letter Manager is active.
- Verify letter_manager.php and hooks files are present and readable.
- Check PHP syntax and the CRM application log.
- Load an admin page to run the schema guard.
- Reopen the sidebar.

EvidenceVerify the history row, PDF, email metadata, open evidence, signature, public page, client view or postal fields produced by this flow.
Rules the system enforces
- The sidebar is registered on admin_init.
- Missing or fatal hook files can prevent menu registration.
How to confirm it worked
- The requested letter, template, setting, file or tracking detail is created or updated through the supported route.
- The history row, generated PDF, email/send metadata, public verification, signature evidence, client view or postal display agrees with the action.
- Any warning, missing file or failed send is investigated rather than bypassed.
Security, privacy and operational checks
- Apply least privilege and verify recipient identity before sending or exposing public links.
- Protect PDFs, enclosures, signatures, verification URLs, email-open metadata, IP addresses and customer data under organisational policy.
- Test configuration and deployment changes with controlled records before production-wide use.
- Interpret email opens and e-signatures according to their documented technical limitations.
