Broken 'Your Comment'

Hello

From a few days all my contributions, active and already closed, do not display provided comment. In field 'Your Comment' I can see only “There was an error fetching the comment.” Is it a known issue? Do you also see that?

EDIT: Looks like it's back to normal, comments are visible again :)
