How to change theme from backend

1) Change directories

cd /var/cpanel/users

2) A look in a users file, list contents of directory
ls for the directory contents then type

pico username (replacing username with an account name)
You should see something like this:

BWLIMIT=524288000
DNS=usersdomain.com
FEATURELIST=default
IP=yourIPhere
LANG=english
MAXADDON=0
MAXFTP=3
MAXLST=0
MAXPARK=0
MAXPOP=2
MAXSQL=2
MAXSUB=0
OWNER=hosting
PLAN=SubWS
RS=x
STARTDATE=1085847520
SUSPENDTIME=1086171449

What we�re interested in changing is the RS value.

3) Changing the user theme
The first is the theme you want to change from, the latter is the theme you want to change to. In this case we want to change Tree skin to x2 skin on all user themes as some of our resellers are using an older skin.

replace RS=tree RS=x2 -- *

4) Make sure that the changes have taken effect by opening one or two of the user files.

pico username


Then ctrl+w to search: type in RS

You should see the new Cpanel theme.
