I'm still a member, still sole admin, have posted nothing breaking the rules. I can like a post or comment, but Facebook will not allow me to make a post or comment (including on a post that I made). I have refreshed the page (multiple times), and logged out & back on.
I can still post and comment on my personal page and on my biz page, but not in the group that I run. I reported the problem to Facebook and got an automated answer.
You are currently permitted to post up to 63,206 characters on Facebook in a status group or wall post. There is no difference.
In September, we increased the character limit on status updates to 5,000 characters. Today, we're announcing that you can now write posts with more than 60,000 characters. (1)

I set the exact limit to something nerdy. Facebook … Face Boo K … hex(FACE) - K … 64206 - 1000 = 63206 (2)

On each post there is a timestamp at the lower right, usually after the number of comments and likes on the post.
Click the timestamp and you'll be taken to a page focussing on just that wall post like so:
From there you can keep clicking "View previous comments" to reveal all previous comments.

This bug was introduced by update 2.3 pushed march 25th. It was due to the introduction of the
user_postspermission involving post permissions on pages and was hotfixed within the day of the update. A good practice in troubleshooting is to always refer to the changelog when you encounter a bug. Usually bugs like this show up and are squashed within hours of the patch due to the massive community that facebook is.
