cPanel error: Session cookies invalid

cPanel is very concerned about security, but sometimes this can cause accidental blocks on your hosting. If you are trying to log in and you get an error on the cPanel login screen that says Session cookies invalid, then one of the cookies for the page is incorrect.

 

To resolve this problem, first clear out your browser's cache and browsing history. If you still have issues, use a completely different browser than you normally use and that should bypass the problem.

 

You can also choose to use an anti-caching mode, such as an incognito window (Google Chrome) or private browsing (Firefox, Safari).  

 

Finally, you can try logging in by going to the following link: server:2083/ and enter your hosting username and password.
