Page in blank everytime I try to add new product (?)

[sofiagg]

Good night, and sorry for my bad english.

Everytime I try to add a new product, or modify it, when I click the SAVE button, the new page gets totally in BLANK. It doesn't matter if I click Save or Save and Stay, the result is exactly the same. So I checked out  my debug errors: 

 

Warning: Cannot modify header information - headers already sent by (output started at /home/ghihtkbi/public_html/config/defines.inc.php:1) in /home/ghihtkbi/public_html/classes/controller/FrontController.php on line 654

Warning: Cannot modify header information - headers already sent by (output started at /home/ghihtkbi/public_html/config/defines.inc.php:1) in /home/ghihtkbi/public_html/classes/controller/FrontController.php on line 655

 

These two previous lines state the following:

 

// Don't send any cookie

Context::getContext()->cookie->disallowWriting();

 

if (defined('_PS_MODE_DEV_') && _PS_MODE_DEV_ && $_SERVER['REQUEST_URI'] != __PS_BASE_URI__)

die('[Debug] This page has moved<br />Please use the following URL instead: <a href="'.$final_url.'">'.$final_url.'</a>');

 

$redirect_type = Configuration::get('PS_CANONICAL_REDIRECT') == 2 ? '301' : '302';

header('HTTP/1.0 '.$redirect_type.' Moved');

header('Cache-Control: no-cache');

Tools::redirectLink($final_url);

 

 

The error is indicated in these three last lines.

In SEO+URL I have already changed all the possible options and it still doesn't work.

Warning: Cannot modify header information - headers already sent by (output started at /home/ghihtkbi/public_html/config/defines.inc.php:1) in /home/ghihtkbi/public_html/classes/Tools.php on line 132

 

 

Now the tools error:

 

public static function redirectLink($url)

{

 

{

if (strpos($url, __PS_BASE_URI__) !== false && strpos($url, __PS_BASE_URI__) == 0)

$url = substr($url, strlen(__PS_BASE_URI__));

if (strpos($url, 'index.php?controller=') !== false && strpos($url, 'index.php/') == 0)

$url = substr($url, strlen('index.php?controller='));

$explode = explode('?', $url);

$url = Context::getContext()->link->getPageLink($explode[0]);

if (isset($explode[1]))

$url .= '?'.$explode[1];

}

header('Location: '.$url);

exit;

}

 

I think that the problem might reside in possible code problem of the languages: On the one hand “es”, and on the other “sp” (for español, or spanish).

 

I have already made several trials and in the english language I didn't have problem when introducing the new products, so I think that the problem may be there, but I don't know how to fix it!!! ANY SOLUTIONS PLEASE?? I'M STUCK HERE and I don't have any idea of what to do! :S 

 

Thanks in advance
