Hi,
Did you successfully install the base demo content in Theme Options -> Import/Export? If not, try this, Go to Tools -> Import -> WordPress and use this file http://take.ms/hqNDo ( don’t unzip it, upload that the downloaded file in .gz format ),
make sure you have high values for memory allocated to PHP https://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP and higher execution time https://wordpress.org/plugins/wp-maximum-execution-time-exceeded/ after successfully install the plugin you may revert back to the original value.
and if that is successful then go to Theme Options -> Import/Export and install the Sports “Demo Version” there,
If you still don’t work it and you are on Share hosting means, ask your host to turn of the safe_mode for some time and try the import process.
Let us know,
Thanks,
laranz.
