Well, I did not solve the problem completely. Here the progress:
new install - fail
added shipping to checkout workflow in the same field with address - manuell shipping plugin enabled - new install - fail
added shipping to checkout workflow moved it to a seperate line - activated all 3 shipping plugins - new install success
At least I thought so, but the bug returned. I can now give you more feedback:
With Australia and or Manuel Shipping Plugin (I never edited that so far, as we have all in prices)in the Checkout Step Adress - Shipping the "new" button redirects to home and you cannot select a Shipping Adress only a billing adress.
With the UPS Shipping Plugin enabled (doesnt matter if the other two are enabled or not) you can enter a new adress and you can select a Shipping adress
However you can never choose a shipping method and i get the error message that now shipping method was selected...
