Why did a feed stop working or breaks my sites validation?

Understand the "garbage in, garbage out" principle: not all feed generators generate valid feeds 100% of the time. Source servers might go down, changes are made - usually these are temporary issues.  If there are invalid characters or other HTML issues in the source feed, nukePIE probably won't correct them.

When a feed stops working, there are several things you can do:

• Verify that the feed is displayed correctly using an un-cached reader (e.g. your browser or another feed reader that hasn't previously displayed the feed).
• If the un-cached feed is displayed correctly, clear the cache files (not .htaccess or index.html) in the /cache directory and it should display correctly again. If it still doesn't display correctly, post a message in the nukePIE forum.
• If not:
  • Report the problem to the feed generator with as much detail as you are able to determine.
  • If the error is displayed in the block, change the block to only be visible to admins until the source is displayed correctly.
  • If the error is displayed in page source or in a site message log, change the block permissions or simply ignore it.
