My site screen turned blank. Pls help.

Hi,

Till evening my site https://www.aboutdehradun was ok but now when I try to open it my site is blank. When I try to type https://www.aboutdehradun.com/wp-admin it takes me to my another site dehradunjobs.in. Iam not a technical person and in the evening I was trying to figure out login issues with my another site dehradunjobs.in in my go daddy hosting account. I think I have messed up some thing. Go daddy support said that they feel aboutdehradun.com’s wordpress database configured with dehradunjobs.in’s database.

I hve no idea what to. pls suggest a solution how can I get my site live. My one year of hard work is at stake.

Regards,

Narender
