just tested on a fresh SMF RC4 and putting the country codes in gives the same errors.

I'm gonna go ahead and say this is a bug.

Quoteplus a token verification failure when trying to take them out and save the page. .

I didn't get the that error.

I also get the error when visiting 'Features and Options > General' if the country are input.

Ok BG thanks, I'm not good at reporting bugs at GH 

Report it at SMF and first see what they say.

I can if you want.

The post has been answered by Sesquipedalian, So if you enter US,GB instead of USA,GB the errors are stopped 

Quote from: SesquipedalianThis is being tracked at https://github.com/SimpleMachines/SMF2.1/issues/6844.

The problem is that "USA" is not a valid two character ISO country code, and SMF currently doesn't check whether the country codes supplied by the admin are valid before it tries to feed them to the [tt]timezone_identifiers_list()[/tt] function. This will be addressed by adding some validation checks on the country codes.

In the meantime, you can avoid this on your forum by using valid two character ISO country codes. The help text for the "Show time zones from these countries first" setting includes a link that will help you look up the correct country codes for the countries you are interested in.

Seen the post and nice to hear.

They should check to see if the codes are ISO 3166-1 alpha-2. You are mixing ISO 3166-1 alpha-2 and ISO 3166-1 alpha-3

Thanks, I've had a look at his fix. It will cause bugs you can't  take the first 2 letters of a 3 letter code. Some countries 2 and 3 letter codes change.
E.G Bangladesh's 2 letter is BD its 3 letter is BGD if you substitute BGD to BG that is Bulgaria.

They might want to look at the 1st and 3rd letter they might match better?

Maybe we should direct someone to this topic so they can see your idea.
