From various responses from visitors to TPV, it appears that the comments are now working again.
PG has a few working hypotheses for what caused the comments crash, but hasn’t come to a definite conclusion yet.
PG uses a well-regarded security plugin called Wordfence to keep bad actors away from TPV and help keep the site running properly. (PG has no idea why TPV would be on anyone’s list of sites to hack because it’s not an ecommerce site, but bots will be bots.)
TPV runs on WordPress, a commonly-used open-source blog software program. A couple of days ago, WordPress had an update which PG promptly installed as usual.
The people who know more about these things than PG does advise installing WordPress updates promptly after they’re released to take advantage of the latest fixes for the program, which often include improvements in security. WordPress provides access to beta versions of new releases to allow people who have more time and knowledge about WordPress than PG does to discover any kinks, problems, etc., prior to the general release of the updated program.
Apparently, the latest Wordpress release and Wordfence initially had relationship issues that resulted in problems for would-be commenters on TPV.
It appears that, with the help of suggestions from several regular visitors to TPV, that the problem is now resolved.
One of the emails PG received after announcing that commenting was back indicated that the commenter had been unable to access the comments function on TPV for some time.
Hearing that sort of thing bothers PG because, as he has said multiple times in the past, he regards the comments as the best part of TPV.
If anyone has problems making comments in the future, please let PG know via the Contact link at the top of the blog. Usually, it’s a problem he can fix easily and he’s happy to do so.
