Glad your test websites are working, but ours isn't per the example image and link provided. : / Now, today, the inline comments are completely gone. All I did was shift their location.
UPDATE: The inline comment icons now appear but there are TWO problems.
ISSUE #1.Some of the associated comments are missing. For example, wpdiscuz-feedback id="n5py894css" has several inline comments (Comment #304, 300, 298, 297) made around October 17. Now it only displays 1 comment.
ISSUE #2: The quoted comment or excerpt does not appear in the comment feed at the bottom. Here is a screenshot I took on October 28 of a comment by Christine Parker. It quotes wpdiscuz-feedback id="n5py894css". Open it today and all the quoted text is gone.
October 28 - quotes inline comment text
November 4 - inline comment text now gone
The associated ID and correlating comments have been disconnected from each other or something.
