In cpanel, you should be able to see how much of your hosting space is being used. I run into that problem when I get too many log files built up…so I have to clean them out periodically. I would look into that and see if you have enough free space.
It’s working fine on my end as well. I second what Ines said…try a different browser. If they work, try to empty your browser cache and reload the page.
