There's a couple of things about that you should know. First one is that it's possible to not have a cookiebanner if you just have anonymous statistics. You need a cookie banner only if you plan on tracking people's IP adresses, or more.

Second thing is that it's illegal to have a "cookie wall" as they call it. Your content has to be able to be viewed without having to consent to tracking cookies. Otherwise it would be akin to a hostage situation where you basically have to use cookies.

Yep, for me it's a white screen. I'm running uBlock origin and Ghostery on Firefox.

For me it only gives a full-screen "by using this websites you agree to cookies" dialog, with only an OK button.

This is not how it should usually go in the GDPR.

Note that the GDPR does not ban all cookies without consent. Some may be absolutely required for the functioning of the website, and are thus allowed without consent. An example would be cookies to save language preferences. Technically speaking, the GDPR doesn't even mention cookies. It just says consent has to be asked when the website is processing PII that isn't strictly necessary for the functionality.

That said, once you do process PII that isn't strictly necessary, you must ask for consent, and you must also provide an option to decline.

The form as such with only an Ok button doesn't allow me to figure out whether these are necessary cookies, and if they aren't it doesn't allow me to decline.
