CPanel seems to disable SourceGuardian frequently when updating (which disables Fantastico), this how-to gives the steps necessary to get it working again.Example of error message:
PHP script /usr/local/cpanel/3rdparty/fantastico/includes/enc_restrictions.inc.php is protected by SourceGuardian and requires file ixed.lin.4.3.10.pxp. Please read SourceGuardian protected scripts manual.
|1.||In your Cpanel WHM, under 'Server Setup', click 'Tweak Settings'|
|2.||In the 'Software' section, make sure that 'sourceguardian' is selected and hit 'Save' at the bottom of the page.|
|3.||Log into SSH as 'root' and run: /scripts/upcp|
After you have completed these steps and the script in SSH finishes running, check your Fantasitco again.
