Domain Mapping Not Working - Parse error: syntax error, unexpected T_STATIC in Domain Mapping Plugin

I just updated our site and now domain mapping is not working. I read some directions about sunrise.php being the problem. I downloaded the latest from your site, but still domain mapping is not working.

Seems related to this one: https://premium.wpmudev.org/forums/topic/problem-with-domain-mapping-i-followed-the-forums-but-i-am-unable-to-solve-it?replies=15#post-753842

I've given y'all access to our network (http://romneymarketing.com) if that helps. Thanks.
