It is fine now. Thanks. But for a whole day I was unable to access wp-admin. I wonder why does it happen?
Thanks guys for help. Resolved this issue. Here is what I have done.
1: exported .xml file.
2: created a new directory for theme.
3: activated theme and imported .xml file.
I am running same theme on a different website. Both have same WordPress version. But I am facing this issue on only this website.
