I've used a dummy account to see the problem appear in our Server Error Logs and found this.

I do not know if this is related to an add-on I've installed, or completely something else.

That's an unusual error to be triggered when registering.

What is max_allowed_packet set to in my.cnf?

Does it occur with add-ons disabled?

It seems like you must have had a whole ton of registrations or something unexpected was stored in the DNSBL cache (which could be from an add-on I suppose).

It should have cleared itself up in an hour, but you should be able to resolve it by running this query:
Code:
DELETE FROM xf_data_registry WHERE data_key = 'dnsBlCache';

Oh question I'm a bit lost of where to run the query.

Oh, sadly not I previously didn't had access to the dedi server, and everything else were already uploaded before I had access.
Mainly use FileZilla.

Anyways, how would one run the query through SSH, I'm still a novice with this.
