How to Assign Permissions to Files and Folders in cPanel

Troubleshooting High Server Loads

One of the more ambiguous, but oft-seen, errors resulting in support tickets is related to high server loads. While high server load errors are virtually never caused by the cPanel software itself or the apps it installs, these errors can certainly carry a degree of frustration.

Generally speaking, this investigation will need to be done by the server owner, their system …

How to Configure and Manage Let’s Encrypt in cPanel

However, we also made it …

In our increasingly busy world, we’d be lost without email, calendar, and contacts apps to communicate, collaborate, and manage our time.
