I suspect it's doing it again,.....hope it can be eventually remedied.

Ty Sarah, all is back to normal, I mean as normal as it can be 

This is happening to me as well, no up or down votes for last 2 days (I at least get a downvote every day), i can see my comments if i return to the page, but I suspect no one else is seeing them AT  ALL.
A fix or suggestion would be marvelous. Thanks
