I had that problem with chat. The problem I saw was websocket connection issue, which would also be the cause of the attendance counter problem. This problem is probably due to old cached temporary internet files.
To fix this problem, I decided to do delete my temporary internet files ('clear browsing history' and select relevant options). You could just hard-refresh ('Ctrl+F5' maybe) the page, which should also fix the problem? :)
