Hi,
you've changed the signature of this function, but haven't updated all calls to it.
Quick greping through sources reveals two more calls to this function that you should update:
public/_lib/class.Api.php:				$this->mJobs = $job->ApiGetJobsByCompany($params['company'], $params['count']);
public/page_job.php:		$compjobs = $job->ApiGetJobsByCompany($info['company'], 5, false);
