On any of our 2.4 installations we get the following errors when we try and use ?Showqueries=1 or ?debug=1 it is getting a little frustrating anybody got a solution?

[User Warning] Cookie 'bypassStaticCache' can't be set. The site started outputting was content at line 159 in /home/XXXX/public_html/sapphire/dev/Debug.php

GET /products/subcategory/?showqueries=1

Line 33 in /home/XXXX/public_html/sapphire/core/Cookie.php

Hey, i have met the same problem with bypassStaticCache on upgrading silverstripe 2.4.
Everything works fine on my local dev model(Wamp server) but met this problem when upload to the live server.

The error message:

[User Warning] Cookie 'bypassStaticCache' can't be set. The site started outputting was content at line 33 in /home/clicknz/public_html/ssnew/mysite/code/ToursBrandHolder.php
GET /ssnew/tours/

24          $path = ($path) ? $path : Director::baseURL();
25
26          // Versions of PHP prior to 5.2 do not support the $httpOnly value
27          if(version_compare(phpversion(), 5.2, '<')) {
28             setcookie($name, $value, $expiry, $path, $domain, $secure);
29          } else {
30             setcookie($name, $value, $expiry, $path, $domain, $secure, $httpOnly);
31          }
32       } else {
33          if(self::$report_errors) user_error("Cookie '$name' can't be set. The site started outputting was content at line $line in $file", E_USER_WARNING);
34       }
35    }
36    
37    /**

Anyone got any ideas?!
Thanks

I found similar when moving between two servers - my UniformServer WAMP dev platform and some ISP of unknown settings. It was not version specific - affected both 2.3.7 & 2.4... but only for two modules I had written.

Turns out to be possibly bad php formatting that was possibly ignored by the WAMP but was noticed in many other core modules: the _config.php seems to require no trailing php closer ("?>"). Removing that from my _config.php and all was well. Very odd! Will check any other faulting modules for same in future.
