Here's the same page on my 1.6 Alpha install:

http://www.brendoman.com/dev/blogs/index.php?tempskin=_rss2

One difference is that mine says version="2.0" and yours says version="1.0". I don't know if that helps.

*cackle* A-ha! Thanks muchly! This triggered the thought process that fixed it!

The error was in the _config.php file, which, during installation, I copied-and-pasted from the web browser because of a permissions glitch. But I made sure, as the script specified, to remove all white space at the end of the pasted section.

I utterly forgot to check for white space at the top of the file, before the "<?php" statement. Two newlines and one tab were throwing everything into a tizzy, and now that it's removed, all is fine.

It wasn't the version numbers, but somehow that got me thinking on just the right track. Thanks much for the assist!

this bug is here in 1.9.3, i view this error message

up please

Your blog has no syndication feeds of any kind. Please clarify your issue and provide a link where we can see it happening.

Wrong, my blog has a feed, TicTac skin doesn't have link rel balise.

the url of this feed : http://theblog.ath.cx/?tempskin=_rss2

I think this is a whitespace issue. The <?xml should be the very first thing in the file, but there are a couple of blank lines first. This affects the rdf skin, too.

http://theblog.ath.cx/?tempskin=_rdf

So there's probably some whitespace getting rendered by some file that comes before that. Ed, any ideas on how to track that down? theblog, have you edited any core files?

um... No. The tic_tac skin - http://skins.b2evolution.net/192/a.php?skin=tic_tac - has the lines in the head section of the _main.php file and the syndication block found at the bottom of the sidebar. Your version of it doesn't, but the skin on the skins site does.

Anyway if you've got whitespace in your feed files that'll hurt feeds from working. I'd start by looking at the _main.php file for the feed "skins" to see that they do not have an extra lines or spaces before the opening <?php thing. It might be easiest, and will certainly be quickest, to simply download the zip package again and unzip it so that you can replace the four feed "skins" from your server and upload new ones in their place. That will ensure your feed-generating files are correct, and possibly cure the problem.

If it doesn't cure the problem it certainly rules out anything in those files!

I use a very old version of tictac skin. I uploaded the 1.9.3 archive too, i have still the error but the files has uploaded today. Only the /inc/VIEW/*.php files are modified for restric the administration panel, no links with RSS feed

theblog,

Most if not all of the inc/VIEW/ files get included before the rss feed is rendered. If you added any whitespace to those files that is sent to the browser before the beginning of the feed, then it could cause this problem. Try this. Backup your changed files and copy the originals back in. If the problem goes away, then redo your changed one by one, testing it after each one.

or, add this to the very top of your _rss2/_main.php

<?php
session_start();
?>

You'll still get an error, but at least you'll know what file it's in ;)

i've uploaded the original b2evo,
I always have the error,

Hi Im facing the same problem and i have found where the problem is
I validated the feed and found out that it IS a whitespace problem so I checked the \blogs\skins\_rss folder and viewed the contents of the _main.php file and sure it had many lines before the xml tag was echoed

So I tried removing all spaces before the xml tag and then it either displays nothing at all or it shows an empty xml document. Any clues? Coz im gouin crazy either the xml doesnt work or the php doesnt work

EthicalHacker : those lines you deleted aren't causing your original problem, what you need to look for is any spaces ( or other characters ) before the <?php at the top of the page. Try opening your page in notepad to check it ;)

theblog : If the error message was exactly the same after adding the code I posted then that would suggest that you possibly have a corrupt file, try reuploading inc/model/skins/_skin.finc.php and seeing if that cures it.

I uploaded thi file but I still have the error

Try this, find this section ( near the top ) of your _rss2/_main.php :

if( !defined('EVO_MAIN_INIT') ) die( 'Please, do not access this page directly.' );
skin_content_header( 'application/xml' );    // Sets charset!
echo '<?xml version="1.0" encoding="'.$io_charset.'"?'.'>'; 

Change it to this :

if( !defined('EVO_MAIN_INIT') ) die( 'Please, do not access this page directly.' );
//skin_content_header( 'application/xml' );    // Sets charset!
echo '<?xml version="1.0" encoding="'.$io_charset.'"?'.'>'; 

Save it, reupload it and see if you still get the error.

this arror affect, RDF skin, RSS skin, RSS2 skin and atom Skin

when i do your modif, i view in my source code :

I view the 2 blank line in all skin.
What is the file was touched by this error ?

That's what we're trying to find out ;)

Change the same piece of code to this and see if your error changes :

if( !defined('EVO_MAIN_INIT') ) die( 'Please, do not access this page directly.' );
echo 'hello world';
skin_content_header( 'application/xml' );    // Sets charset!
echo '<?xml version="1.0" encoding="'.$io_charset.'"?'.'>'; 

hello world is at the line 3

But my principal skin are 2 blank line too

Here's another whitespace problem:
http://forums.b2evolution.net//viewtopic.php?t=11326

There was another one this week, too, but I can't find the thread now. theblog, do you have error reporting turned on? Add this to your /conf/_config.php file:

error_reporting(E^ALL);

Then that session_start() code that YaBBa gave you will spit out an error that tells what file is inserting the whitespace.

It's the error message I'm looking for. Can you redo it ?

¥

*edit*
Morning Dan ;)
That's what I'm trying to work out as well :p

The problem was fixed

Great news. What was your solution? If other people with the same problem find this thread, your answer could help them.

Wehn i'm install the paginator hack(1,2,3,4,5) for select page, i included whitespace at the end of _hacks.php file in the /cof directory
