Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

When creating an RSS feed, org-publish broke for me with

  signal(error ("Not an Org time string: "))
  error("Not an Org time string: %s" "")
  org-parse-time-string("")
  org-time-string-to-time("")
  (format-time-string "%a, %d %b %Y %H:%M:%S %z" (org-time-string-to-time 
pubdate0))
  (if pubdate0 (format-time-string "%a, %d %b %Y %H:%M:%S %z" 
(org-time-string-to-time pubdate0)))
  ;; …
  org-rss-headline((headline ... ...) #("<p>\nIch bin ei..." 4 395 ... 407 410 
... 492 530 ... 534 535 ... ...) (:export-options nil :back-end ... 
:translate-alist ... :exported-data #<hash-table eq 836/4001 0x20766a9> 
:input-buffer "rss-feed.org" :input-file "/home/arne/Sch..." :description "" 
...))


Maybe relevant: I have date enabled in options.
#+OPTIONS: date:t

Best wishes,
Arne
