Because some of my problems, I performed the following script.

Code:
/scripts/rebuildhttpdconf
To the script, I was faced with the following error.

Code:
info [rebuildhttpdconf] User 'USERNAME' data set has no 'main_domain' key.
And now following problems occurred.
1 - Web site instead, default Cpanel page is displayed.
2 - In the List Accounts of WHM, rather than show IP, is shown MISSING

How to solve problems?
