Dropdown menu for Country list

Hi, I've sent message before but nothing is being done.
I still can't use the country list on the site. Every time I search country I get a "The website is temporarily unavailable. Please try to access again in a few minutes. Thanks for your understanding." but everything else works just not the "Country dropdown menu. Any help? Thanks

Did you see my reply on there - I solved the same message myself.

Is that the page you are trying to get?

Right-click on the pink part - the actual tab, not the address bar below it.
Then select the green part - Unmute site.
That worked for me.

​Thanks, but I don't have 'Unmute site' I have a mute site. So I click on it then went back and click unmute site. Either way didn't work. Any other suggestions?

Not from me - I solved mine by accident - but would like to
see what other members suggest in case it happens again.
Not sure how it happened, or what unmute site means anyway.

Also cannot remember if mine got solved straight away, or I had
to switch the computer off then restart it.

OK, fixed. Works now. Turned it off and on several times and didn't work. This morning looked and it worked.
Thanks for the help.
