Notice: Trying to get property of non-object in /home/saveresc/public_html/wp-includes/link-template

The error appears at the bottom of this page;

I'm using CIvicrm and WPMU Dashboard. I've tried disabling all plugins but still no go.


I upgraded civicrm from 4.2.1 to 4.3 in order to see if that was the was not, the issue remains.
I also added require_once('pluggable.php'); to the - /home/saveresc/public_html/wp-includes/capabilities.php but removed it once the site was upgraded. Issue remains!

Thank you in advance for your help!
