问题 I am trying to regain access to my databases stored in CouchDB, but the error This database failed to load. gets shown instead of the databases (see attachments). I started seeing all of these errors at once It be some user rights misconfiguration (1. The error This database failed to load. is normal, when lacking privileges, 2. The actions to delete or replicate a DB are missing). However, I am logged as admin. Can you help me find the root cause of the error? Simple PUT and DELETE requests

FieldOne: cow FieldTwo: pig FieldThree: dog When creating a mango index for the query what fields should I use? Should I create and index with multiple fields? Does the order matter? There are also three different document types (A, B C) defined in a field. I only need to

I keep seeing the following screen after restarting the image
