Still not Nick.
I've installed CB then CBSubs (module, system plugin and all CB plugins (main, content, promo, tax, ...)).
I've clean the cache of my site and on my PC and more, I've used IE (I never use it).
Then I display a plan (f.i.
www.aesecure.com/fr/index.php?option=com_comprofiler&task=pluginclass&plugin=cbpaidsubscriptions&do=displayplans&plans=1).
I make a new user registration. The country is well, by default France.
I click on "Save". CBSubs show me the first screen (see attached file).
No VAT there and no VAT too if I continue to the next screen (PayPal).
I cancel the order and click on "Click here to change the billing address".
There, in that edit screen I do nothing at all except click on save.
And, bingo, CBSubs display the VAT.
So : nothing has changed; same situation. No VAT applied for new users.
(please don't forget my question "How CBSubs should be configured to use the buyer's country rate in EU?" I really don't know how to do that magic stuff).
Thanks, have a nice evening.
