You want it 'fixed fast' (fine) but you aren't giving more detail or the screenshot so we can actually *see* what the problem is. Therefore you're just making it take longer to get your problem fixed :/ So now we can only guess at things that might be causing your problem.
Since you haven't even bothered to tell us what browser (and version) you're using, or whether you're using it on a computer or phone, I will assume you're on Firefox on Windows.
3. Check that your date and time settings are correct for your operating system. Make sure to synch your time with an internet time server as well. If the date/time is wrong, fix it and then clear your cache.
Without more details of course we can't be more specific sorry.
Just for info, this morning my ISP connection dropped out in the middle of doing things.
Following that when i logged back in, my gym did not work and looked like the screen shot below with the gym menu missing on the right side.
I had too fully re install java and reboot before i got things back to normal.
Hope this helps
