[SPAM] Unable to change bounce processing

I'm running qmailadmin 1.2.16 (with vpopmail 5.4.33), and when I click 
on an account's catchall button or otherwise attempt to change the 
catchall status for the domain, it simply returns a blank page without 
having changed anything. The url appears to be properly formatted, and I 
see what appears to be a normal message in the apache access log. I'm 
running QmailToaster on several hosts, and they all have this problem.

Will someone be so kind as to tell me how I might troubleshoot this?

TIA.
