Finish PHP MySQL CMS Directory website

I have a project that is partly complete. The HTML/CSS is all complete but the functionality does not appear to work anymore. It is a directory website that uses CMS to maintain some of the content. The project used to work correctly but does not anymore. It is possible that the MySQL database will need to be reverse engineered from the code. I require the project to be fully functional including: Search using Google Maps API Members sign up, login and forgot password Paypal payment Automated renewal reminder emails/switching off of members that do not renew Admin section with: Login Option to turn members on and off Update content for the website I believe all of the functionality above is implemented and should not need much work. The project appears to use: FCKEditor Javascript Joomla PEAR Smarty Wordpress No SEO or styling needs to be done.
