AJAX Comments/MailPress Causing PHP Errors on Submit of Comments

(Thanks for the tip-off, Kim Flournoy!) MailPress seemed to be causing an error whenever someone would try to post a comment to my site.  The comments were actually getting through, but the commentor would see the mess of PHP errors below.

Upon deactivating MailPress, submitting a comment would result in a blank white screen (called a white screen of death in some parts).  I deactivated AJAX Comments (just a hunch) and the blank screen was fixed, and I was able to re-activate MailPress without any problems.  To summarize,

The problem is AJAX Comments, not MailPress, or at least the two don’t play nice together.  I choose MailPress as the one to keep and AC as the one to blame.
