error, when i want to go my feed

You have a blank space/line at the beginning of your feeds.
It can be casued by a plugin, by editing a file etc.

First, try to deactivate all your plugins. If it works, activate them one by one and check which one is the culprit.

I have activated all my plugins one by one, but i couldn’t obtain normal feed work. Please, what to do next?

It might be in the feed generating files then. Or in the short and sweet index…

It’s very good, but i cannot understand it)) i’m just a beginner at blogging. Could you rewrite your previous post more detailed?

I have the same issue in all of my WP installations…

i.e:
https://www.lateleencasa.com.ar/?feed=rss2
https://www.giossa.com/?feed=rss2
https://www.ecomercosur.com/?feed=rss2

I tried to modify the php pages that “create” the rss feed, looked the index.php page, but I can not find where is the error.

I use WP 2.3.1 but I had the same problem using previous versions.

My installation is simple. I create a hosting account, I copy the WP files (upload via FTP) and nothing else. WP works fine allways, but the RSS feed doesn’t work.

Seems FeedWordPress does this to my site, deactivating it retrieving a feed, and reactivating it solves the problem for a week or so

If a plugin has blank lines at the beginning or end of the plugin file, it can cause this problem and break other things as well.

Edit your plugins and make sure none of them has blank lines at the beginning or end of their PHP files.
