I did a handful of updates today, 8 of them appear to be fine.
the 9th (of course, mine) has an issue:
only wp-feed.php is returning with a feed.
domain/feed/ (which usually works) is a blank page
as are the other feed pages (even when called directly)
replacing htaccess with a fresh file (re did the permalinks)
deleting the files and re installing them (ran upgrade.php again too, and it let me)
deleting the files again and re installing them
only deleting the rss related files and re uploading them.
Is anyone else having this issue?
I'm surprise that the other 8 are operating just fine, but this one is clunky.
