Site not working - SBC

Hello our site is www.sbcconsulting.in and was built using your theme.
All of sudden the site is not working and also unable to login the admin panel.
For more than a year the site was running well. Your help would be appreciated.
I am willing to share FTP details in private if you want in private.
If it doesn’t fall in your purview then it’s fine and I can understand.

Hello,

It doesn’t look like a theme issue, you can try to contact your hosting provider support and see what they say. Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
