LMS is not displaying any new published changes

[mzia (Mudassir)]

Hi everyone,

I am facing strange issue with tutor latest release, where LMS is not displaying any new published changes. Only top level Section is displayed however subsection(s) and unit(s) are not visible to the students.

Screenshot from Studio

and LMS

CMS and LMS workers logs, not sure if this is normal?

I have tried following workarounds but none of them have helped.

1. Server restart
2. tutor local restart
3. Troubleshooting — Tutor documentation
4. tutor local run cms ./manage.py cms force_publish ..

Could anyone please guide what else I shall look for?I have observed logs there are no errors when it comes to existing course.
For existing subsection(s) we are able to add new units which are working as expected.

Thanks!

Hello @mzia,

Check LMS and MFE logs, those logs would be helpful to find the culprit.

And also check the status of your services using tutor local status.

What version of open edX are you running?

@pdpinch I am running nutmeg.1.

Thanks @jramnai. I did check the logs and there were no errors.
“tutor local status” was okay i.e. required services were up.

I restarted the tutor and noticed that cms_worker logs were not flowing, stuck on

celery@edx.lms.core.default.%879aba223501 ready.

I am not sure if this is bug, I restarted only cms_worker, after that the LMS started to publish the changes as expected. I have noticed that I had to do this step whenever I restart tutor local or do stop-start.
