Can’t modify an account through WHM

When you go to Account Functions >> Modify an Account and try to change the username of domain, sometimes you may get the following error.

Error.. There is currently a configuration error in the Apache configuration file. User name change aborted.
Account modification aborted, there was a problem changing the user name.

For the fix, go to ‘tweak settings’.
*Under ‘System’, choose “Max cPanel process memory” –> The maximum memory a cPanel process can use before it is killed off.
*Set to higher value. To 256MB is enough, then click save.

Now try to change the username 🙂
