I'm implementing my first Silverstripe site but I get this XML error when I try to see my site with Firefox 2.004 (the site works fine on IExplorer 6 and on my PSP browser), my hosting is Dreamhost

The URL for my SS site is: www.naciondnb.com/site/
The homepage is: www.naciondnb.com/site/home/ (based on article_holder)

The error is (sorry it is in Spanish):

Error de parseo XML: intrucción de proceso XML no se encuentra al inicio de la entidad externa
Lugar: http://www.naciondnb.com/site/home/
Línea 3, Columna 1:<?xml version="1.0" encoding="UTF-8"?>
^

Screenshot: http://www.naciondnb.com/error.jpg

Othe pages are:
http://www.naciondnb.com/site/agenda/
http://www.naciondnb.com/site/audio/
http://www.naciondnb.com/site/bio/

Hope someone could help me!

XML Parsing Error: xml declaration not at start of external entity
Location: http://www.naciondnb.com/site/bio/
Line Number 3, Column 1:<?xml version="1.0" encoding="UTF-8"?>
^

The problem with the error means you've got some lines before the <?xml tag, which is only allowed on the first line in your template.

There seems to be some blank white space at the top of your document before the <?xml tag. Please try removing this and see if it makes any difference.

Cheers,
Sean

Thank's Sean for the help, I'm trying to find where to remove the blank lines, I've checked the page.ss template and the XML declaration is at line 1 of the code, wich other files could be causing the blank lines??

Hmm, that's strange... I've never had that problem before.

Have you also tried ?flush=1 at the end of the URL, perhaps it is caching somewhere?

Cheers,
Sean

That problem often occurs when you start writing php

if you have a php file like this:

<?php
....
....
....
?>

with a blank line after ?> then you can be in trouble .... If you changed any of the php files,I would check those ...

Yes I did flush, I think is actualy a error in one of my templates called audio_holder
made based on article holder and with the same principles from the tutorials.

I publish the page www.naciondnb.com/audio/ with that template and the error appears, when i publish it but i choose not to show it in the main menu, everything's fine.

I'll try to figure out what's wrong with that template and i'll let you know!

Thank's for the help!!!

Thank you so much Nicolass!!!

That was the problem, I removed a pair of blank lines after the ?> in my AudioHolder.php file, and everythings is fine now!!!

Thank´s again!!!!!

I just had the same problem when I downloaded a SS site from a live server (Linux) and put it back on a WAMP server I got the error on the login page, I checked all of my PHP code and template to no avail as I don't really code in such a way that allows spaces below the closing PHP tag :)

The problem I found was in quite a few files in the sapphire/security/ directory.

I guess someone (a dev) needs to go through all of the SS core files and either remove the PHP closing tag or remove the white space(s) below it.
