When Atom reached 1.0 I updated my Atom 0.3 feed to a 1.0 template I found on the internet. Unfortunately there was a bug in it. I don’t know if it ever worked? I thought it did… well, now I’ve fixed the bug in the given template.
While debugging this I managed to delete my crappy Swedish “bortsupet” post so I cannot give credit to the person that notified me that there was indeed a problem on my end.
