cPanel, error logging in with Safari
Some users are unable to access the cPanel dashboard after logging in with Safari on a Mac
Users have reported that they are having trouble accessing cPanel using Safari on a Mac.
Users are able to log in using the Campus Login button, and are forwarded to the page that lists their accounts. Clicking on one of these accounts redirects the user to the login page and shows an error similar to "Illinois Azure did not return an authorization code. Log in to Illinois Azure again."
Use an alternate browser such as FireFox or Chrome.
We have opened a case with cPanel support. Their developers will provide a fix in a future release of cPanel.
