I'm trying to install a WordPress export, I can get as far as choosing the authors and selecting upload file attachments but I can't go any further and the import fails. I just see a white screen.
The URL for the white screen is:
If I go back I see an error page:
Sorry, there has been an error.
File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini or by post_max_size being defined as smaller than upload_max_filesize in php.ini.
The file definitely isn't empty and below is my php.ini:
upload_max_filesize = 128M post_max_size = 128M memory_limit = 128M max_execution_time = 600 max_input_vars = 10000 max_input_time = 400
