If your having issues getting past step one (the installer page) on Fantastico, there are a couple of reasons why:

Licensing: Please make sure that you have obtained a license. If you have not, please contact support and they should be able to work with you on obtaining one.

Register Globals: Inside the WHM, you want to make sure that register globals are disabled; otherwise Fantastico will be unable to complete the installation. To enable them, please do:

• Login to the WHM
• Click on "Tweak Settings"
• Find "cPanel PHP Register Globals (Off [unchecked] is recommended for security reasons)"
• Please ensure that its disabled

Ioncube: Under the same "Tweak Settings" please ensure that you have IonCube enabled. If you don't then Fantastico will still have the installer problem.

• Login to the WHM
• Click on "Tweak Settings"
• Find "Loader to use for internal cPanel PHP (Use oldsourceguardian for version 1.x and 2.x)"
• Enable "IonCube"
• Save
