Shopping cart hangs on checkout [resolved]

Update: This appears to be related to a DNS issue, but is fixed now.

It has the same problem.
Although the checkout hangs, the order appears in the database and confirmation emails are sent.
The host says it's not a hosting issue.

Any help would be much appreciated!

Hi Tahiera,

Can you show me how did you configured your Checkout through some screenshots ? ("Hikashop->System->Configuration->'Checkout'" ?

Thank you.

Thanks for looking into it!

Any suggestions on how I might fix this or find out what's causing it? I can give the login information privately if needed.
