On 9 August 2019 an issue with Django Q was identified:
If you initially built Ghostwriter before or around the same time as this issue was reported you may notice the
queue container's logs repeat
ERROR unknown attribute: "days" and scheduled tasks show the last run results as a grey
? badge. This is caused by the container using the latest version of the
Arrow library that is incompatible with your version of Django Q.
This issue was resolved (see the GitHub issue thread) but you will need to rebuild your Ghostwriter containers with
django-q==1.0.2 to make sure you have the version with the fixed code.
