Ok,
I have disabled the "Show Prices" and the shop works .
* For me the word "Default" is misleading - I think this word is the standard setting for a new user. They are automatically given this group when registered in the shop.
* So for a first time user of the VM shop I would then look everywhere to ensure that everything is set to "default" - I would go into the shop ( products), I would set the taxes the same and try my best to make every thing "default" -
* For long term users - we know that you do not have to do this _ but it is very unclear -
*To fix this my suggestion is the: word that needs changing is the VM users - "default" wording in the users section - It needs to be a word like "user" or "registered" .
* Elsewhere there needs to be in the back end - in products and in the taxes, etc a small written script that says
" you do not need to set shopper groups for the shop to run" I would put this wording in the shopper group section. You have a lot of room at the top of the shopper group section. maybe the first line says that- but the rest is a clear explanation of groups is needed.
