Are these issues connected?

[r€nato]

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
