Can't finish Demo Data Import

The most common problem is the timeout issue which is caused by a low-value set to some php configurations. See here for more info

Make these values higher than default. Example:

  • max_execution_time = 300
  • max_input_time = 300
  • upload_max_file_size = 256M
  • post_max_size = 256M
  • memory_limit = 256M

These values are not perfect and it depends on how large of an import you are making. So the bigger the import, the higher the numbers should be.
