You may have noticed that over the last week or so I’ve been having problems with my rss feed.  This occurred at the same time I upgraded to Wordpress 2.9.1.

I was getting various errors but mainly the ‘Warning: Cannot modify header information – headers already sent by (output started at line…’ error.  I tried everything from removing spaces in php files to reinstalling feedburner plugins.  Still, nothing seemed to work.

Today I thought I’d test something else.  I went to my Wordpress dashboard settings, clicked permalinks and hit save.  The default option was already selected.  That was it – and for some reason my feeds are working again.

I don’t know why it went wrong or how that helped exactly as I’m no Wordpress expert but thought I’d share my experience in case anybody has encountered the same issues.
