I had problems with my site not saving. I submitted to WP

I had problems with my site not saving. I submitted to WP Dev and got told it was something in my server. I changed servers. Now after a week of going back and forth, changing servers, and having my sites down only days before an event and then DURING the event everything has finally cleared the servers and propagated only to give me an error warning.. the same error that was coming up in my error logs prior to changing servers.

Warning: Invalid argument supplied for foreach() in /home/scottwha/public_html/reifa/wp-content/themes/upfront/library/models/class_upfront_layout.php on line 224

I would really appreciate some help in FINALLY getting this cleared up. Support access has been extended on the multisite. Main site reifa.org -- site showing error is reifacon16.reifa.org.

I'm a little confused why I am only getting this error on one site and not all sites using the theme.
