Adress Tab in the configuration dissapear ?

Hi,

That option should always be set to "individual". We removed that setting as people were not using it properly.
We only left it for people who had set it to something else so that they cna go back to the default value it should be or leave it as they had it set.

So you have two options:
- you go in your PHPMyAdmin, open the hikahsop_config table, and modify the value corresponding to that option so that you can get it back.
- you fix your tax rules so that it works properly with the individual type as it should be.
