So you would have to remove the immutable bit before restoring its contents. Here's the reversion procedure:
chattr -i /usr/local/cwpsrv/htdocs/admin/design/css/custom.css
cp /usr/local/cwpsrv/htdocs/admin/design/css/custom.css /usr/local/cwpsrv/htdocs/admin/design/css/custom-dark.css
truncate -s0 /usr/local/cwpsrv/htdocs/admin/design/css/custom.css
nano /usr/local/cwpsrv/htdocs/admin/design/css/custom.css
chattr +i /usr/local/cwpsrv/htdocs/admin/design/css/custom.css
