my hosting said this
In this case we feel there is little or nothing that can be done to repair the file system of this site.
The site was built on WordPress and you do not have a proper backup I believe.
It must be said that, while we ensure that programming languages such as Perl, PHP and ASP are installed and functioning on the web hosting system, we are not responsible for customer programming especially from those purchased elsewhere.
We undertake Web design projects and for these we do offer support for these but anything other than this is a chargeable service.
We would suggest you contact the vendor of this site requesting they reinstall from backup. This will mean deleting and starting afresh.
In this instance we are sorry we are unable to assist.
