[BlueOnyx:20122] Problem with non-www A records

[DD]

Hi all,

I have two websites affected by a problem with A records. These also happen
to be (the only?) two websites affected by the PHP problem I mentioned in
[BlueOnyx:19799] PHP breaking randomly.

Briefly, the following two links should work, but instead go to a subdomain
on a different site:

	http://executive-transfer.co.uk
	http://tidetimes.org.uk

The www versions of the same links work fine. Both sites have 'Web Alias
Redirects" ticked, and I have unticked/re-ticked both, saving each time.
Both use Let's Encrypt certificates.

The first did not have an A record on the server's DNS when I checked and
I'm not sure if this was always the case or something that has changed
recently. 

Versions:
# cat /etc/redhat-release /etc/build
CentOS release 6.8 (Final)
build 20140909 for a 5208R in en_US

Any ideas would be very much appreciated.

All the best,



Dick Dolby
