Hi,
I had installed a plugin PrimaryFeedburner and setup so that my WP feed was hosted by Feedburner.
I get a 403 from this URL http: //feinsteaktien.de/aprilwetter-an-der-borse/ if I click on the title in Feedly. I converted to Feedly which imported my GoogleReader feeds.
So I am not totally sure where this 403 comes from but after disabling PrimaryFeedburner and accessing the feed directly from my WP site everything runs smoothly now.
Here is the error which was logged:
>>>>>>>>>>> 403 GET or Other Request Error Logged - 22. April 2013 - 08:37 <<<<<<<<<<<

After deleting the last part with “utm_campaign” I did also NOT get the 403. So I suspect it has something to do on how Feedburner inserts the utm_campaign field.
Maybe this is of interest to you.
