Problem with importing demo of Consulting theme by Stylemixthemes

I have just tried to import a demo of Consulting theme by Stylemixthemes but a message appears “Error 500” Internal Server Error. I can’t upload no demo.
The problem is that yesterday my support expired and there is no longer possibility to get in contact with the support team.
You buy a support for one year and the day after you can’t get any help. There is no longer any forum for Stylemixthemes customers.
Does anybody have any idea how to resolve the problem of importing demo.

Thanks. I installed Wordpress again and then the theme. At the end I imported the demo and the problem disappeared. It must have been a problem with installation before.

Thank you for solution actually i was also stuck at 99% :slightly_smiling_face:
