Troubleshooting Queue errors

If problems are encountered:

1. enable the queue log and then inspect its contents
2. check the queue_master.php scheduled task is present and its next run date is in the future

Enabling logging

Logs are disabled by default to minimise the load on production servers and must be enabled when investigating an issue.

To enable logging:

1. Log into your server, either by SSH or RDP depending on your environment.
2. Open config/logs.xml in a file editor
3. Change the enable attribute value to true for the queue log entry
4. Save the changes and clear the application cache.
