The Internet world is fast moving forward and scripts and technologies change to keep up with latest developments. Same happens with Joomla, one of the top free CMS scripts out there. The other day my web hosting provider announced me that they will update the server PHP version to 5.4 and that I should upgrade any old scripts as they might stop working. On that hosting account I do have some websites that were built on Joomla 1.5, and unfortunately this version of Joomla is not functional in the new PHP 5.4 environment.
