ok, so the problem is actually not in the postcode plugin, but in the update of the main plugin to 2.16.11.20
that update however was done to deal with an issue in the postcode plugin when using other settings, so the whole thing is a bit circular (i’ll spare you the details)
what i’ll have to do – and admittedly probably should have done to start off with – revert the changes made in 2.16.11.20 back to 2.16.11.19 and really fix the issues in the postcode plugin that appeared with the settings i alluded to above
confused yet ?
anyway, i’ll sort this out asap
