Hello,

I have upgraded kibana from 7.13.2 to 7.16.2.

No plugins installed.  
Environment:

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/0/9043146d184a2d82acfdbfcbeeeb226872945c9b.png)

Error:

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/0/c/0c28441e50a479ad7dcbb49f836c98b6c1d06056.png)

There was an error in logs:

```auto
 {"type":"log","@timestamp":"2022-01-11T09:22:44+00:00","tags":["error","plugins","eventLog"],"pid":8,"message":"error setting existing \".kibana-event-log-7.13.2-000004\" index aliases - error setting existing index aliases for index .kibana-event-log-7.13.2-000004 to is_hidden: illegal_state_exception: [illegal_state_exception] Reason: alias [.kibana-event-log-7.13.2] has is_hidden set to true on indices [.kibana-event-log-7.13.2-000004] but does not have is_hidden set to true on indices [.kibana-event-log-7.13.2-000007,.kibana-event-log-7.13.2-000006,.kibana-event-log-7.13.2-000005]; alias must have the same is_hidden setting on all indices"}

```

I delete all kibana indexes because it was not important for me

```auto
curl -XDELETE localhost:9200/.kibana*

```

But the same error is still presented. Session and browser cache cleared.

I also try to totally remove the container via

```auto
docker-compose stop kibana
docker-compose rm kibana

```

But still the same error.

What can be a problem?

Thank you.

The problem was with Cloudflare cache. After purging Cloudflare cache, everything works fine.
