Since we switched to CDN a long time ago and demo import files are not bound to the download file, we regret to inform you that at the moment Bridge users won't be able to do demo import.

This problem is reported and technical service from CDN is working on fixing this issue.

We hope it will be resolved in less then 24hours Thank you for understanding.

T_PAAMAYIM_NEKUDOTAYIM Fatal Error

That is usually an error related to your PHP version on the server. Try contacting your hosting provider and ask them to increase your PHP version to the one suggested by wordpress here: https://wordpress.org/about/requirements/

For this error, PHP version 5.3 would be enough to work well.
