Permission problems
Similarly, wrong permissions also create problems. For instance, in one of our customer’s cPanel servers, LVE failed to work as the file /var/cpanel/cpanel.config had incorrect permissions. This prevented LVE Manager from displaying the user limits correctly. The right permissions for the file should be 644. Then only, LVE can read the data from the file.
Reason For Error:
In short, LVE manager not working error happens due to package problems or wrong permissions.
Solution For Error: Run This Command:
yum update lve lvemanager lve-stats lve-utils lve-wrappers
