Fantastico installation on WHM

SSH in to the server then : 

cd /usr/local/cpanel/whostmgr/docroot/cgi
wget -N http://files.betaservant.com/files/free/fantastico_whm_admin.tgz
tar -xzpf fantastico_whm_admin.tgz
rm -rf fantastico_whm_admin.tgz

A number of issues with Fantastico all have exactly the same cause and solution, so please try these two simple steps if you're having any problems with Fantastico either not working, displaying errors such as disabled functions or saying that Fantastico isn't installed in the correct location:

1)  Log into WHM as root, click on Tweak Settings, scroll down to the PHP section and make sure the      IONCUBE PHP Loader is selected. Save changes if needed.

2)  Log into your server as root via SSH and execute the following command:
    /scripts/makecpphp

For step number 2, make sure that the script completes the task without any errors. If the script stops the installation with errors, please deal with those errors before continuing.

We've seen a lot of servers lately that have cPanel and WHM incorrectly using a server's frontend (public) php.ini configuration instead of the correct backend copy located at /usr/local/cpanel/3rdparty/etc/php.ini. Running /scripts/makecpphp will fix this problem so long as your cPanel installation is reasonably up-to-date. Also, some people have missed the IONCUBE step mentioned in our installation directions or have accidentally had the loader changed or removed.

Reminder: Setting the IONCUBE loader in Tweak Settings does not affect your public PHP configuration, only the backend copy used by cPanel and WHM
