On our blogs sites, legitimate comments are being posted by readers. However, within the past few weeks, the comments are being inexplicably wiped clean after a short period of time within posting--seems like within a few hours or so. The comments are not being deleted--that is, not being completely removed from the site--they are just automatically being wiped clean.
So, say John Doe, makes a comment. After a short while, the content of the comment gets cleared/erased, leaving a blank spot next to John Doe's name in the comment section.
The only thing that I can see in the Comment History for each comment is "Akismet cleared this comment" when it was posted.
Does anyone know if this is a known issue and what can be done to fix this? I'm completely puzzled as to what may be causing this. And since comments are being cleared, I have no way of looking back to see what was said in order to see what may have triggered the spam filter (or whatever may be the issue).
Here is a post on one of our blogs which is being affected:
At the moment, there are 4 comments in this post alone which are now blank. And, again, this is happening on a number of our blogs in all posts with new comments which use the default WordPress comments feature (as opposed to IntenseDebate, which we use on a few of our blogs, as well).
Lastly, I did just update some plugins this morning (including Akismet) as part of troubleshooting.
