I see a "Forbidden" message, what do I do?
If you're seeing a page that just says "Forbidden" when trying to access your account, you'll need to clear your browser DNS cache. (This is related to a recent denial of service attack on Chartable.)
If you’re on a Mac, open the Terminal app and paste in:
sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder
and then click enter.
If you're on a Windows computer, open the Command Prompt app and paste in:
and click enter.
That should clear your browser cache and resolve the issue.
