Fantastico is an additional component for CPANEL that may be added to your web hosting account. This feature enables a web site owner to quickly install dozens of the leading open source programs and content management systems into their web space, with little or no technical knowledge.
It will basically give you a list of available programs and install them with one click.
It sounds very appealing for the newcomer to webiste building as there is little or no work required for setting up.
Some problems worth noting are as follows:
1- Many web hosts do not update these scripts. I have seen many fantastico scripts offereing xoops 188.8.131.52 version when the latest is 184.108.40.206!
It could take you longer and require more initial expertise to update this script that to install the latest version manually.
2- Some web hosts will configure all the fantastico scripts to install onto one database. Not a problem, but may cause a headacke with maintenance later, plus DB backups can become very large.
3- There have also been reports of fantastico installers not setting correct permissions for certain files/folders.
Treat Fantastico with some caution, especially if an older script version is offered.
