I just got the 419 error message about five times. Two posts today, the message interrupted on both
posts on the initial "submit post" attempt. In editing the first post i got the error message twice again.
"419 PAGE EXPIRED" is a nuisance. That i just grabbed from yours.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
