Maybe you’ve noticed that the sign-in block is missing from the post, so it isn’t obvious how you can sign in now. If you’re not signed in, you can’t comment or add new posts, so this is important. I have no idea what happened here, but it looks like some sort of automatic update was applied that changed a few things. I’ll have to research it.
In the meantime, I was able to sign in by attempting to leave a comment. The option was presented there to sign in, which worked. Hopefully that will work for you also. If it doesn’t, maybe someone could let me know through email.
Very strange. It’s Trump’s fault somehow, I’m pretty sure.
