Views exposed filter error "An illegal choice has been detected. Please contact the site administrator." I am having a very odd problem with an exposed filter in one of my Views. The page I am talking about is here: http://epsindustry.org/eps-packaging-map2

When I select one of the last 2 options in the menu (EPS Packaging Recyclers or Loose Fill Recycling Drop-off) I get an error that says An illegal choice has been detected. Please contact the site administrator. This is really weird to me because it only happens with these 2 options. I don't believe they are set up any differently than the other taxonomy terms. There's nothing all that special about them, its just a term that the admin selects when creating a location for the map.

Any ideas as to why this is happening or how to fix it?
I was having the same issue. In my case the 'illegal choice' message was displayed when changing the country from 'United States' (the default value) to 'United Kingdom' and selecting 'North Yorkshire' as state/province and saving.

I did the following to fix it:


Go to the Configure page of the Location field (by editing the node type and going to 'Manage fields').
In the 'Events settings' section (not the 'Locative information' section), there is a drop down group called 'Default value'. I set 'Country' to United Kingdom.
Save field settings.
Done.
