However, as of this morning I am unable to do any Search.
With VPN on or off? If on, goto the URL opera://settings/vpn. Do you have Opera set to bypass the VPN for default search engines or no?
Did you install any extensions in Opera?
And whats with the SpamWall? Blocked from registering unless I give permission to receive non-relevant emails?
That was added because of https://gdpr-info.eu/ regulations. It's just saying that you agree to forum notification emails for watched posts etc.
