I'm surprised this has happened and there has been no rollback. cPanel has always had a reputation for taking the time to implement new features for quality reasons but in this case it looks like no testing has been done and no one has bothered to undo the change. I appreciate they may be working to fix it, but as a developer I would at the very least roll the change back and, while people can use the system as normal, work on a fix in the meantime. Don't understand why this hasn't happened? Some clarification would help please...Same here, our firm has already received numerous blowback's on social and well as direct complaints by phone and trouble tickets.
I would this this would to be an immediate fix.
