Demo Import goes to blank screen

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.

Hello there,

It seems that you have low PHP directives on your hosting plan.

Common problem with Import can be WordPress memory limit and upload time, and it is good if you can increase these values or ask your hosting service to do that for you.

max_execution_time = 300

memory_limit = 128M

upload_max_filesize = 64M

post_max_size = 256M

Increase the values as much as you can, since they can be limited on shared hosting plans.

Install this plugin in order to check your current values.

Check import functionality afterwards.

Best Regards!
