Works best to import on a new install of WordPress, after installing if any trouble comes up, please reset your WordPress and start from the beginning.
There are some settings that are needed to be checked before importing demo content, please check the following values in your php.ini file:
Memory Size: memory_limit = 256M Script execution time: max_execution_time = 400 Number of input variables: max_input_vars = 4000
If you don’t have access to the php.ini file, you can add the following values in your .htaccess file:
php_value max_input_vars 4000 php_value max_execution_time 400 php_value memory_limit 256M
Be careful using these settings, some hosting companies don’t allow users to change php settings, if you experience any problem after making these changes, please revert these in your .htaccess file, using your FTP client.
