wordpress website hacked – what to do?

Hello,

My wordpress website got hacked (probably), here’s the URL: Fashion Allure

the problem is that after entering the site, there’s simply nothing

I re-sent the files from the install pack and it helped me get the access to control panel, I mean wp-admin, so I made a backup of the wodpress contents

unfortunately I have no idea on what could be changed. I checked the config file and it looks perfectly fine, so I tried the re-install and the upgrade but I already have the latest version

I have also lots of plugins and I wouldn’t like to lose it all and reinstall it again, I’m simply looking for a simple yet clever solution

Please please help!
