¿ Puedo restaurar mi pagina web, unicamente con mi Base de Datos?

Hola a todos los de la comunidad, espero me puedad colaborar, hace unos dias unos Hackers me borraron la página y solo tengo la base de datos.

Hice una instalación con la la plantilla que tenia antes y restaure la base de datos que me quedo, pero aun asi no me funciona y me salen unos errores, pues lo pensado era que solo los errores serian por las fotos que no estan, pues como hice una instalacion nueva o definitivamente tengo que instalar todo desde ceros?

Estos son los errores que me salen en la pagina:

Warning: Invalid argument supplied for foreach() in /home/arteyarc/public_html/web/libraries/joomla/plugin/helper.php on line 46

Fatal error: Call to a member function get() on a non-object in /home/arteyarc/public_html/web/templates/beez_20/error.php on line 11

y si ingreso por el admin me salen estos:
