No Comment Notifications After Upgrading WordPress?

In November I posted a tip for those of you who might not have been receiving notifications when someone commented on your WordPress blog after upgrading it. Well, guess what? WordPress still hasn’t fixed the problem, so if you’ve upgraded, you need to put the fix in again.

I found this out a few days after I upgraded earlier this week. A couple of days went by and no notifications were sent. It wasn’t until I went to my Comments tab in my admin control panel that I saw some people who had left comments for me (bless you!).

That’s when I remembered that the file, pluggable.php, had been replaced with the new one during the upgrade. The good news is that the same fix still applies. All you have to do is go to line 228, which looks like this:

$phpmailer->Sender = apply_filters( 'wp_mail_from', $from_email );

and comment it out to look like this:

//$phpmailer->Sender = apply_filters( 'wp_mail_from', $from_email );

So if you’ve recently upgraded to 2.3.2 and had this fix in place earlier, you may need to update it one more time to receive notifications again.
