jlehrer on "[Plugin: Quick Page/Post Redirect Plugin] 500 error when attempting to bulk import"

When trying to upload an import file, I get a 500 server error.

To make sure the file was in the right format, I manually added a redirect, then exported it in text format, then deleted the redirect, then uploaded the exact file I had downloaded. Got the same 500 server error.

Plugin version 5.1.5
WP 4.4
PHP 5.4.24
Host: Bluehost

This is the file I tried to import. It's just one line and it's formatted like this because the DNS hasn't been switched yet from old site to new site.
