After I upgraded to 5.6.1.2 I see this error on ever page of my web site:

Fatal error: Class Job contains 3 abstract methods and must therefore be declared abstract or implement the remaining methods (Concrete5_Model_Job::run, Concrete5_Model_Job::getJobName, Concrete5_Model_Job::getJobDescription) in /home1/accountname/public_html/sitename/models/job.php on line 5

Other than it showing up, everything else seems to work fine. Does anyone know how to fix it?
