When I import the demo xml, it goes straight to a blank Import Wordpress screen. If I refresh, it will give me this error:
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.
I thought that I may have been getting the error because I was interrupting the import process, but it does not seem to matter how long I wait - the blank screen remains blank.
