How I can convert my CSS theme to use it in Xoops?
Xoops is very capable of using tableless layouts with CSS. This FAQ is beyond a simple 'how to' answer, but we suggest you look at other tableless themes to see how the CSS is used. Take a look at http://www.dcdezines.ca/ for some inspiration and tutorials.
A large number of XOOPS sites that are hacked are because the owner failed to set the correct file system permissions on critical XOOPS files and folders.
