Debug Canvas LMS errors

Locate log files

The Canvas LMS logs are stored at the log folder inside the CanvasLMS installation directory: /opt/bitnami/canvaslms/log/production.log and /opt/bitnami/canvaslms/log/delayed_job.log.

Troubleshoot upload/attachment errors in courses

If you are running Canvas LMS in a Unix system and you experience errors while trying to upload or attach a file or an image to a course, it may be due to the sticky bit in the /tmp folder. Canvas LMS performs a couple of operations in the folder /tmp while uploading a file or an image, and it requires the sticky bit to be set on that folder. To enable it you can execute the following command:

$ sudo chmod +t /tmp
