I have not heard of such a problem. Can you retry by following the instructions provided in this video uploaded by me.
Hope this solves your problem. If not email me a temporary login through my profile page in ThemeForest and I can take a look. Pls make sure the theme is installed in the directory under mydomain.com/wp-content/themes/enigmatic.
I would not try another method since it has worked countless number of times without this issue and unless there is an inherent problem with your wordpress installation/setup, you should not face this issue. It is just a symptom of a larger issue which won’t go away even if you found another way to import data. Thanks.
