Hi,
Maybe it’s possible to login to your site’s admin to check what’s going on? Also FTP access would help a lot. If it’s possible – my private email is [email protected].
P.S. I did try going through your site’s frontend, however I keep getting “VAT is not valid” message (I’ve tried VAT ID you’ve provided, and I’ve added FI prefix). If you have checked “Check country by IP” checkbox in plugin settings, then my IP being not from Finland would result in invalid VAT..
