When a file is uploaded through the cPanel File Manager on a CloudLinux server, you may encounter the following warning:
"An error occurred. Your account may be over its quota or you attempted to upload a folder."
This error may occur if the account attempting the upload is over their inodes limit as set in CloudLinux's LVE manager.
Adjust the account's limits as outlined in our support article, How to adjust Inode limits via CloudLinux's LVE.
