Thanks very much to Ron and Bob for thir suggestions. That PHP changed
between releases was my suspicion as well, and this may confirm it.
Bob, the change to $a_pref[value] fixed the issue. One thing I wasn't
clear on was whether I should insert a value in the brackets, or actually
type [value]. Not knowing what the value would be, I did the latter. And
it worked, so it looks like I can go live with my new site.
Thanks again for the suggestions, which I will forward to the maintainer
of that plugin as well.
Regards,
Ed
