500 Error

[controlshiftgithub]

Hi,

I have the latest version of YOURLS and have been able to activate all plugins except this one. I am getting a 500 Error when clicking activate.

I am using Chrome and have tested on IE as well.

After clicking activate, I receive a 500 Error. The url that causes this error is

http://myurl/admin/plugins.php?action=activate&plugin=yourls-bulk-import-and-shorten&nonce=mynonce
