Error with page updating and post.php

I updated to 3.8.1 about a week ago, and now when I try to update a page (I click ‘update’), the browser kicks back a white (blank page). Then if I try to navigate back to any admin page of the site, it kicks back the same blank page. I then have to wait about a minute – navigate to a new page (i.e. Google.com), and then re-enter at wp-admin. Most of the time the updates to the page are lost, but every once in a while I do manage to do a successful page update – but this rare. I’ve had the same error in Safari and Opera – in Opera I get the message that the server dropped the connection. I host with GoDaddy, but I haven’t been able to find any error logs that are relevant. Any thoughts?
