I am running a DNS and DCHP service on a local server (Raspberry on Stretch).

When checking the zone files, I get:

# [2019-02-03 10:32] maxg@rpiserver /etc/bind/zones $
named-checkzone rpiserver argylecourt.org.db
argylecourt.org.db:22: ignoring out-of-zone data (argylecourt.org)
argylecourt.org.db:23: ignoring out-of-zone data (argylecourt.org)
zone rpiserver/IN: has no NS records
zone rpiserver/IN: not loaded due to errors.

This is the contents of the argylecourt.org.db zone file:

; Host-to-IP Address DNS Pointers for argylecourt.org
; Note: The extra “.” at the end of the domain names are important.
;
; $ORIGIN .
$TTL 86400 ; 1 day
; rpiserver.argylecourt.org. IN SOA rpiserver.argylecourt.org. hostmaster.argylecourt.org. (
@ IN SOA rpiserver.argylecourt.org. hostmaster.argylecourt.org. (
 2019020203 ; serial
 8H ; refresh
 4H ; retry
 2W ; expire
 1D ; minimum
)

; NS indicates that rpiserver is the name server on argylecourt.org
; MX indicates that rpiserver is (also) the mail server on argylecourt.org
argylecourt.org. IN NS rpiserver.argylecourt.org.
argylecourt.org. IN MX 10 rpiserver.argylecourt.org.

;$ORIGIN argylecourt.org.

; Set the address for localhost.argylecourt.org
;localhost IN A 127.0.0.1
;localhost IN A 192.168.1.7
rpiserver IN A 192.168.1.7
www IN CNAME argylecourt.org

I also have errors in the reverse zone:

# [2019-02-03 10:43] maxg@rpiserver /etc/bind/zones $
named-checkzone rpiserver rev.1.168.192.in-addr.arpa
zone rpiserver/IN: NS 'rpiserver' has no address records (A or AAAA)
zone rpiserver/IN: not loaded due to errors.

... which has this contents:

$TTL 86400 ; 1 day
; IP Address-to-Host DNS Pointers for the 192.168.1 subnet
@ IN SOA rpiserver.argylecourt.org. hostmaster.argylecourt.org. (

 8H ; refresh
 4H ; retry
 2W ; expire
 1D ; minimum
)

; define the authoritative name server
; IN NS rpiserver.argylecourt.org.
 IN NS rpiserver.

[update 1] Have just read: BIND Reverse DNS Ignoring out-of-zone data -- which resulted in 0 errors when applied to my situation.

# [2019-02-03 10:46] maxg@rpiserver /etc/bind/zones $
named-checkzone 1.168.192.in-addr.arpa rev.1.168.192.in-addr.arpa
zone 1.168.192.in-addr.arpa/IN: loaded serial 2019020203
OK

OK

[update 2] restarting bind9 results in:

Where do I need to look to fix this problem?

It's the full stops - in the first file the final line needs to be:

www IN CNAME argylecourt.org.

Without a full stop on the end it'll append the domain name again.

In your reverse zone the penultimate line is correct and should be commented out, the final line with rpiserver. will try and find something called rpiserver as a top-level (no domain after it) - you can also just try removing the full stop but I would use the penultimate one.

Well, this was a newbie error! Sorry.

I started digging further when I realised the old serial number.
I looked up cat /etc/bind/named.conf.local, which pointed to [file "/var/lib/bind/argylecourt.org.db";]
... while I was updating /etc/bind/zones/argylecourt.org.db
Ouch!
Thanks to all for looking into this.
