So I learned from a wanna-be commenter here that efforts to post comments here (am I being redundant by now?) were failing.
Instead of the comment posting, this error message resulted instead: Invalid security token. Bad. Deal.
I did some research in the course of two days. 🙁
I learned that Jetpack Comments does not play nice with Antispam Bee. That’s good to know…but I don’t have Antispam Bee.
I disabled some other plugins, including Live Comment Preview. Nope — the problem continued.
So I disabled Jetpack Comments. Too bad. 🙁 But at least now people can comment here again! (I suppose that will open the floodgates to the comment spammers again. If so, Akismet can earn its keep once again.)
PS: To those of you who tried commenting and experienced the invalid security token problem, I’m sorry. 😥 Please try again now!
Update on October 30, 2012 at 7:43 am — I forgot to mention last night that, before deactivating some plugins, I tried using a different theme.
