error in a cookie, affects search

I get some kind of cookie errors on https://rdmo.readthedocs.io/en/latest/index.html, think it only affects the search.

A Cloudflare cookie?
```js
Cookie “_cfuvid” has been rejected for invalid domain.
```
and
```js
Uncaught ReferenceError: jQuery is not defined
```

maybe some dependency needs an update?
