Blank page when editing a message, posting an answer

[racingparts.ro]

i get a blank page when i edit a message, post an answer.

i checked all the things you advice in the other discussions but with no success.

sometimes everything is ok ..and the page reloads with the answer added or the message posted ...but more times i get the blank page

do you have any other suggestions?

i overwrote the forum files with the files from the backup i made 6 months ago, hoping that it will solve the problem ..but it doesnt

Please see the link below for known causes of blank or white pages:

i did almost every thing on that list except:

11. Check your phpinfo page to see if suhosin is installed as a module. If it is, this could be the cause of this problem. To fix this, add or edit an .htaccess file in your root forum directory and add these lines to it:

php_flag suhosin.cookie.encrypt Off
php_value suhosin.request.max_vars 2048
php_value suhosin.post.max_vars 2048

12. This can be caused by a bug in PHP 5.2.5:

http://bugs.php.net/bug.php?id=43620
6. Your PHP has magic_quotes_sybase turned on. You have to turn this off. On *nix systems you can do this by creating an .htaccess file with this content and placing it in your main forum directory:

php_flag magic_quotes_sybase 0

i dont know how to do this

If you go to AdminCP > Maintenance > View PHP Info, search on that page for the term 'suhosin' - is it there?

Also, what version of PHP is shown at the top of that page?

[racingparts.ro]

PHP Version 5.2.14
no suhosin found on that page

What's in your server error logs for the time that you get blank pages?

<?php
define('DISABLE_HOOKS', true);

should i remove one line at a time and see which was the problem? or is not important?
