Hello,
Thank you for your report, we'll fix this in next version.
In the meantime, you should be able to fix it using following steps:
1. In the same file, find this line (it should be around line 1400):
function _parseAlias($route, &$vars)
2. Remove the ampersand character, so the result will be:
function _parseAlias($route, $vars)
That's it.
Best regards,
ARTIO Support Team
