I upgraded from silverstripe 2.4 to 3.0.5. At the beginning, all seems to work fine, after I upgraded my site like documented. At a certain point, my site seems to crash the admin area. The site is running fine, only the admin area isn't function. When you try to edit a page of the site you get wired text out put and the admin area stops working. Pressing the reload button, all is fine, I can edit the page, pressing save, the same picture. I need to reload. I took a screen shot of the wired text look.
Any idea?

Thanks for your help!

My admin area Pages section also like this. If click on any functionality nothing happens. When I refresh the page it will display. Any solutions?

Solved the issue.
Remove whitespace before an opening tag, or after a closing tag, in one of the project PHP files.(mysite/code/<php files>)

This is EXACTLY the issue I'm trying to resolve (actually I've been trying for a couple of weeks)... I thought I was the only one having this problem!

I'm trying to add an editable sidebar to my site. I"m using the following Page.php which validates fine. However when I load it I get the same issue as you had. I've tried to re-key to remove any extra spaces -- now it crashes out my DB rebuild at SiteTree (Gah!). Frankly it's giving me the sh*ts -- SilverStripe is a great package but I'm a designer who can code -- not a developer. Plus while I can find my way around and cut and paste code, I can't write php functions from scratch...

So tell me -- which 'opening' and 'closing' tags are you referring to? The <?php and ?> tags? Or is it a spacing issue within?

Must you have a space before a {?
Do you not have a space before a (?
Can you see any issues with the attached?

Any advice appreciated...

<?php
class Page extends SiteTree {
	public static $db = array(
							  'SidebarHTML' => 'HTMLText'
							  );
	public static $has_one = array(
								   );
	function getCMSFields() {
		$fields = parent::getCMSFields();
		$fields = addFieldToTab("Root.Sidebar",new HTMLEditorField("SidebarHTML"));
		return $fields;
	}
}
class Page_Controller extends ContentController {
	public static $allowed_actions = array(
										   );
	public function init(); {
		parent::init();
	}
}

Well that's progress -- went through code again. Not sure shat I did -- now I simply get an "Internal Server Error'?

Hi arthurdent
Plaease check is there any space or new line before "<?php" or "<?" tag.
also check is there any space or new line after "?>" tag.

I've been advised that SilverStripe does not need a closing tag...

Looked at the server logs and found the error in my code (as confirmed on SS Forums) -- line 10 should be:

$fields -> addFieldToTab("Root.Sidebar",new HTMLEditorField("SidebarHTML"));

My bad...

Thanks for your comments -- can see the light at the end of the tunnel now!!

If there is a closing tag there is no white space after that. Closing tag is not a must.
