Found problems:

1. Cannot edit project, it’s frozen at “Upload Template”

2. Cannot edit project, it puts an error:

>Project folder /var/cpanel/rvglobalsoft/rvsitebuilder/www/project/xxxxxxxxxxxxxxxxxxxxxxxxx is missing!<

Reasons:

1. RVsitebuilder is incompletely updated.

2. The project cannot create symlink.

Solutions:

1. Download RVsitebuilder installer again with force update version again.

cd /usr/local/cpanel/whostmgr/docroot/cgi/

rm -rf /usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/

rm -f rvsitebuilderinstaller.tar

wget http://download.rvglobalsoft.com/rvsitebuilderinstaller.tar

tar -xvf rvsitebuilderinstaller.tar

rm -f rvsitebuilderinstaller.tar

chmod 755 /usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/appconfig/registerapp

/usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/appconfig/registerapp

perl /usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/autoinstaller.cgi --force

After that, try to check edit project. If still doesn’t work, do the number 2 below.

2. Check if your server is running with selinux with the following command:

sestatus

SELinux status:                     enabled

If it's enabled, please set it to "Disable". And run clean folder with the following command:

find /var/cpanel/rvglobalsoft/rvsitebuilder/template -print0 |xargs -0 -n 1 setfattr -h -x security.selinux

find /var/cpanel/rvglobalsoft/rvsitebuilder/www -print0 |xargs -0 -n 1 setfattr -h -x security.selinux

Reference: cPanel doesn't support selinux

http://docs.cpanel.net/twiki/bin/view/AllDocumentation/InstallationGuide/ConfiguringOs#Disable

Important: For cPanel & WHM to run on your server, SELinux must remain disabled. You should make sure that the pound sign (#) does notprecede SELINUX=disabled. If # precedes this configuration option, the line will be ignored.
