Summary of the issue you are facing:
After installation from scratch on clean server according to documents I’m trying to remove all wanings step-by-step. Unfortunetly I can’t get rid of memcache warning and I can’t force Nexcloud to run with Redis memcache distributed → I’ve got internal server error. When I’m switching to Memcached Nextcloud is starting, but warning about memcache is still displayed
Steps to replicate it (hint: details matter!):
- Install NC according to documentation.
- Modify config.php to turn on memcache.
- Check setup
