Dear Jan,
Sorry to hear about your trouble with our plugin and the impression that it does not offer any functionality. Not too long ago, we switched over to WooCommerce’s Shipping zones, which means that the plugin does not need its own frontend any more to addcountry zones and shipping methods / rules, but uses the standard WooCommerce shipping zones.
The functionality of the plugin now appears quite hidden in the shipment method selection box: In the admin area, if you go to “WooCommerce” -> “Settings” -> Tab “Shipping” -> “Shipping zones” -> select a zone (“edit”) or “Manage shipping methods” for “Locations not covered by your other zones” -> “Add shipping method”. The “Add shipping method” dropdown box should also offer the “Shipping by Rules” method, which gives you access to the full power of the rules (sans the mathematical formulas, but still very powerful in the free version). A screenshot can be found here: https://pasteboard.co/H9mlRUF.png
The plugin’s configuration screen (“Shipping” -> “Shipping by rules”, also linked in the plugin area) does not add any additional functionality, but only serves as a different view of the zones, where you quickly see all zones and which of the methods use the Shipping by rules plugin.
Best regards,
Reinhold
