I Need Help

A friend of mine is in a need of assistance with his website he ask me to have a look at it as I develop web sites but not in php format. His former hosts have closed shop and he is left with a problem regarding some of the processes within the site itself, it looks to me he might lost the original templates or they have become contaminated in someway to some of his pages ie news, newsletter and an article link he runs, all these are linked directly to his web site and that link works fine except the pages come up empty and all of the pages are still in the system and can be accessed manually. The site in mention is www.eternalhealth.org if cannot help me direct I am getting to know my way around this site and learning as I go so if you can help in rectifying this problem with either new templates I can recreate the old information that he wishes to display I have the necessary passwords and user names needed for this site and if there is a fee involved for this service I am sure we can meet it. kind regards Charles Wollongong - NSW- Australia
