The RSS feed (website.com/feed) broke on two of my sites. Not sure what broke it; upgrade to 3.5.1? Move to dedicated IP? Removing white space at the end of wp-config.php seems to have fixed it.
What causes RSS feeds to break?
There are a lot of posts about broken RSS feeds with vague solutions, like this one or just do a search on 'broken feed'. The given solution is usually to uninstall all plugins. Some posters report back that they found a plugin that broke the feed.
But I can't find an explanation anywhere why feeds break. Is it that fragile? What can I do to prevent it?
Could the code be updated somewhere to make it less fussy? Does it have to 'fatal error'?
It's a bit weird that a line of whitespace in wp-config.php - or in plugins or functions.php as others have reported - can crash the feed. Is there no way to filter for that?
