In my Analytics account I keep on getting this notifications, Self-Referrals, redundant hostnames and Duplicate Campaign Parameters Issues.
Is it because of 2 Google Analytics code installed on one site? (http://holtcat.com/careers.aspx)
If I will remove the other code should it fix the issues?
Re: self referral
I am not sure about your issue, but You should ONLY have one code on your site, that's for sure.
