Anyway, to fix that I've just turned off the option "display detailed taxes" (you don't need it for what you're selling) in the Display tab of the configuration and it's now displaying it normally.

We literally spent hours banging our heads against the wall trying to diagnose this. Anyway it now works which is the main thing. I'd love to be able to update Hika to the latest version but when we tried (several time), it completely destroyed our layout and menus. We cant figure out why. I sent you an email last week asking if you guys could try to update the 1.5.6 version on our dev server to diagnose the issue. I'm happy to pay for this as I realize it may a problem on our end. Is there someone I could contact to set up a date/time/cost for this?

We would need a back end and FTP access. You can send your request to my colleague jerome at hikashop dot com and he will reply to you for the arrangement.
