Question

RSS feeds are broken on my 4.2 installation. I'm getting the following error from readers:

XML Parsing Error: xml declaration not at start of external entity
Location: http://host.domain.etc/wiki/view/TWiki/Web<nop>Rss
Line Number 2, Column 1:

There is a blank line at the top of RSS feed topics (when viewing browser source), and my research seems to confirm that this causes this XML parsing error.

I've looked at the rss templates, view.rss.tmpl and view.rssatom.tmpl, removed even the comments at the start, and seen no change. It appears that something is causing the newline even before the template is consulted. But normal view pages have no newline at the start. Skin customisations etc seem irrelevant because the feeds run under their own skin entirely.

Any ideas? All our feeds are out of action.

The answer: I developed a COVER skin template to customise some of the UI elements. While newlines don't normally seem to be a problem, newlines near the top, around %TMPL:INCLUDE{"view"}% , introduced an extra newline into the rss output and broke the XML. See TWikibug:Item5426 for more info.
