Comment (by rweil55):

 I had some shortcode code that instead of returning output for wordpress
 to display, it had a "print" statement to send some debugging text to the
 browser.  i.e sending output directly to the browser rather than through
 wordpress.

 Obviously a no-no, but it took me a while to figure out that was what was
 causing the "update failed" message.

 Here is a short code function that will cause the message. Remove the
 print statement, and no message.
 function dothework($atts) {
    print "hello world - should not do this";
    return "this is the right way";
 }

 Hope this helps
 Roy
