====== Why are invitations not being sent? ======

This usually occurs when certain background processes or database configurations are missing or incorrect.

To ensure invitations are picked up and processed correctly, follow these steps:

=== ✅ Required Checks ===

  - **Cron Job**:  
    * Make sure the cron job is running correctly on the server.  
    * If it's not enabled, the system won’t trigger the invitation process.

  - **`fw_invitations.sentdate` Field**:  
    * If the value is `0000-00-00`, invitations have not been marked as sent.  
    * Compare this behavior with a working instance to identify discrepancies.

  - **Index on `sentdate`**:  
    * Go to the **Structure > Indexes** section of the `fw_invitations` table.  
    * Ensure that `sentdate` has a **BTREE index** (e.g., `sentdate  BTREE  No  No  sentdate`).  
    * If missing, **add the index by referring to a working instance**.

=== 📌 Example Scenario ===

> Invitations are queued, but none are being sent.  
> ✔️ On checking `fw_invitations`, `sentdate` is `0000-00-00`, and no index exists on `sentdate`.  
> ✔️ Compare with another working instance, add a BTREE index, and confirm cron is active.
