String used as array

[SiR-DanieL]

In class-wc-ge-ip.php on line 1517 we use $buf as an array but it seems to be a string instead.
This could return errors on some websites, like

Notice: Uninitialized string offset: 0 in public_html/woo/wp-content/plugins/woocommerce/includes/class-wc-geo-ip.php on line 1517

Not really a string.

Maybe this is just the symptom of not having downloaded GeoIPv6.dat file.
You need to check for other error messages because only with that particular line everything is ok.

The error is that the file is missing. I'm investigating more to check why it's not downloaded. We can close this issue for now. I'll reopen it if the issue is with WooCommerce. Thanks @claudiosmweb
