No choice of "state" when editing billing address

As I said in my previous message, the login and registration boxes do NOT overlap on our end. Did you flush the cache of your browser ? Which browser are you using ? If you use another browser, do you still have the problem ?

For the button, it's a styling problem of your template.
You can add the CSS below to correct it:
.art-button-wrapper{
margin-bottom : 20px;
}

Nicolas, I fixed the overlapped "boxes". My main template was set up with 660px width... That's why I couldn't control width through HikaShop css.

Also, thanks for css for button... It looks like the most issues are already solved!!! Thanks a lot for a great support )

I wonder if something similar occurred in the 1.5.3 to 1.5.4 update?

Please don't post your questions through several threads.
