The install of Fantastico on many web hosting servers contains outdated scripts. This leads many people to believe there is a security risk associated with using Fantastico. However, many of the scripts offer easy to understand updating instructions from the main website. Wordpress, for instance, offers one click updating to the most recent version of the blogging software.
Some people also look at the style of software available as a negative. To use Fantastico for free, the scripts included are often open source. Some open source software offers a strong customer service backing while others tend to offer less. Before you choose to install with Fantastico, make sure to research the script you want to install and judge the customer service and security of the script.
