It seems from my reading of the current pdf that you can download, that your manual hasnt been updated since v3.1 of viart!?!
Can you please please update this. Its really vital and im sure will assist you with fewer support queries! It seems that your "shooting yourself in the foot" as the english expression goes by not doing this...
Also, your online shop demo runs viart 3.0 which is now very old. there are many many features i want to propose to clients that I cant demonstrate to them without putting up my own demo shops online. Again I cant understand why this hasnt been updated. Im sure it would benefit you as well as me if your demos reflected the latest new features in the software!
