I am opening a new topic as I haven't received any reply to my following comment under the resolved topic of "Importing posts not working":
I am rewriting in the same thread which is assumed to be resolved already.
We were also successful in importing the demo and the issues were resolved. But very recently we were trying to start from the scratch in a separate fresh demo installation of the leonado theme as the old one has got too much messed up.
After successful installation of the theme and all associated plugin activation, we are no more finding the import demo option like the last time. How can we import the demo data now? Please assist at your earliest convenience.
