List email plugin ajax gives CORS error

[chipperfield]

Hi there.

Fabrik 3.7 on Joomla 3.7.5
On hosted site with an .htaccess which forces any non-www access to be www - ie everything should be www.chipperfieldprojects.co.uk . I did this some years ago specifically to avoid AJAX CORS errors between www and non-www access to domain.

Everything works fine except List Email plugin, which gives the AJAX CORS error below since it is trying to reach www domain from what it sees as non-www domain (but the page it is redirecting from is definitely www).

The Email plugin is a new feature I am trying to add to the site - the rest of it has been live for some years.
Any ideas would be very welcome.
Thanks
Giles

XMLHttpRequest cannot load

Redirect from
'https://chipperfieldprojects.co.uk/...derOrder=2&ids[]=98&checkAll=0&format=partial'
to
'https://www.chipperfieldprojects.co...derOrder=2&ids[]=98&checkAll=0&format=partial'
has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'https://www.chipperfieldprojects.co.uk' is therefore not allowed access.
