I've inherited a Joomla website and have been having some technical difficulties. What started out as a small internal server error has progressed to the point that the website is completely down. Here's a link to the site: http://cnifoundation.org I'm told that the problem can be fixed very easily, but I know nothing about Joomla or PHP and don't know how to start. I'm in desperate need of IMMEDIATE help. Will hire first qualified candidate. Would like to get the problem...
