The error was
Fantastico is not installed at the default location
/usr/local/cpanel/3rdparty/fantastico. Either move the Fantastico directory
from it's current location to /usr/local/cpanel/3rdparty/fantastico OR
enable ioncube loaders in WHM -> Tweak settings.
Enabling ioncube did not fix it for me. Maybe it will for you. After looking I found cpanel now uses /var/cpanel/3rdparty/bin/php NOT /usr/local/cpanel/3rdparty/bin/php
After doing a php info I saw it did not have a php.ini file in the new location. The fix was:
cp /usr/local/cpanel/3rdparty/etc/php.ini /var/cpanel/3rdparty/etc<br />
Other Possible Fixes
You may want to first try enabling ioncube in WHM->Tweak Settings
Second you may want to try to update fantastico with cd /usr/local/cpanel/whostmgr/docroot/cgi/fantastico/scripts/ ; /usr/local/cpanel/3rdparty/bin/php cron.php
Third you may want to rebuild cpanel's php with /scripts/makecpphp
Fourth you may want to try a cpanel update with /scripts/upcp --force
Today I found this error while trying to open Fantastico page in cPanel.
Fantastico is not installed at the default location /usr/local/cpanel/3rdparty/fantastico. Either move the Fantastico directory from it’s current location to /usr/local/cpanel/3rdparty/fantastico OR enable ioncube loaders in WHM -> Tweak settings.
Though I did not do this in my case, if you are facing same problem, first of all, try restarting cpanel.
service cpanel restart
I have made it confirm that ioncube is installed. However, I reinstalled it by following command:
/scripts/phpextensionmgr install IonCubeLoader
This did not solve the problem. Then somewhere in forum/blog I have read it that rebuilding cpanel’s internal php may solve it. I did that:
/scripts/makecpphp
I have restarted cPanel (look above for command) and the problem is fixed like magic.
