Open edX - Quick Tip - Clearing LMS Cache27 Feb 2019
A quick tip that I discovered when working with the LMS on devstack. I would make changes in the Studio but they would take forever to show on the LMS. Restarting the memcached container did the trick:
docker restart edx.devstack.memcached
You will need to sign back into the LMS, but the content will be refreshed.
