We can see that it shows it is modified by question but when we look at the question, there is no modification from Community user.
I thought it was a bump to answer but there's no mention of that in the question's timeline.
Some questions were edited by Community♦ to replace http with https due to network wide https. But there was no question or answer linked in the question.
I was wondering what caused to show that it is modified by community. What was the modification?
