Hey Deb!
Now please don't take offence at anything I say. Not meaning to put you down.
I guess the pros are off for the long weekend, so you're stuck with me by the looks of it.
A website needs regular maintenance and a Joomla website is rather complex, though from what I can see from the remains of the site, it is a fairly basic site, though well designed. A pro job, I'd say.
You'll need a professional web designer, proficient in Joomla. Not much you can do yourself.
Maybe you can contact the person who built the site.
They will need access to your account and site on several levels. Usernames, passwords, host. If you can't track down the person who holds that information, you may as well kiss the website goodbye.
Your webmaster will need to get into the files and see what damage is done. If you're lucky, maybe the hackers didn't delete your database, but you'd have to be pretty lucky. The original webmaster should have a backup, if you can find him.
In the mean time, I'd be buisy copy and paste whatever you can salvage of the content and save it as a txt file in Notepad. Save the images from the front page in a graphics programme. Looks like only the home page images still there.
You'll find the cached version of the sites pages as follows:
Do this search in Google: *site:
www.sundeck.com.au* Just copy what's between the stars, but not the stars, into the Google search box and hit Enter. Click on where it says Cached for each page of the site and copy and paste what you can. Don't worry about the formatting. Your webmaster can easily sort that out. It's the content that matters.
But at the end of the day, if you can't find the original webmaster or if he doesn't have a site backup. I'd say it will need a fresh start. So save whatever you can of the content as a starting point.
Keep in touch. I'll see if I can make a copy and can e-mail it to you.
