Are these issues connected?

I am having three issues related to my store:

1. UPS shipping cannot retrieve a shipping quote.

2. Sales tax is not being figured, it is always zero.

3. I cannot delete a customer. From this page in Admin:
   store/admin/customers.php

the first (and only) customer in the list shows up in the box at the right for 'edit', 'delete', 'email'

I click 'delete' and get the following:

Warning: reset(): Passed variable is not an array or object in /home/content/s/i/g/signalgates/html/store/admin/includes/classes/object_info.php on line 29

Warning: Variable passed to each() is not an array or object in /home/content/s/i/g/signalgates/html/store/admin/includes/classes/object_info.php on line 30

along with the confirm delete message in the box at right

I go ahead and click 'delete'. Nothing happens.

Also when I click on the customer name, I get a page which should (it seems) display all of that customer's stored info. It's titled 'Customers' just below the Admin menu.

This page shows nothing in the fields, where it should (I assume) show that customer's stored info. It also generates the above-mentioned error messages.

I'm currently taking a look at the code to see if something is not being set or otherwise what could be missing.

I can post further details on the admin settings above (e.g., yes UPS module is active) if desired. I'm hoping these three symptoms point to a common problem!!!

thanks in advance

... with regards to the inability to edit or delete a customer, the crazy thing is that the customer id (cID) is getting passed to customers.php?action=edit

shouldn't the customer ID value be enough to retrieve the customer's data from the table???

OK! I have discovered that my hacking of the account creation pages (yes, go ahead and laugh at me) caused 'customers_default_address_id' to not be set in the 'customers' table.

This incorrectly stored field was what caused the UPS module to not work. I have to do a minor edit so that I can get to the sales tax page and see if that is working now. I can now edit and delete customer accounts. Hooray!

Thank you for following up on the problem and the fix.

color me embarrassed!

but hey at least I figured it out.
