Hi.
Thanks for your reply. On the first points, the country code is set correctly, I haven’t been locked out, and I haven’t changed any files / re-installed etc.
I’ve just deactivated and reactivated the plugin (on 2 different sites), and the country code is staying correctly set.
I’ve just tried something else, and think I might have found the culprit. I use infinitewp to manage my websites – deactivating and reactivating it from there causes the country code to be set incorrectly. There must be something different about the way it activates plugins.
Many thanks.
