Problem: In UPS plugin configuration the warehouse settings are not being saved.
So per the documentation I need to set up a warehouse. I give it a name, zip code, and country (units and currency already filled in). I click on save and this information disappears.
I try again this time give it a name, zip code, country, click ADD, then save. It disappears.
I Click add, give it a name, zip code, country, then save, disappears.
Thank you for the report. That happens when you don't set a zone for a warehouse. We've put together a new version which fixes that behavior. If you download again HikaShop and update, that should solve the problem.
