Menu item limit

Hi guys,
in my menu I’ve only 43 item but I can’t add any more. I tried a lot of solution as writing some string in .htaccess or php.ini file but all solutions failed.
These are the strings I tried:

<IfModule mod_php.c>
php_value suhosin.simulation 1
php_value suhosin.memory_limit 128M
php_value suhosin.post.max_vars 5000
php_value suhosin.post.max_input_vars 5000
php_value suhosin.request.max_vars 5000
php_value suhosin.request.max_input_vars 5000
</IfModule>

max_input_vars = 5000
suhosin.post.max_vars = 5000
suhosin.request.max_vars = 5000
php_value max_input_vars 5000

max_execution_time = 90;
max_input_time = 60;
upload_max_filesize = 70M;
post_max_size = 128M;
upload_tmp_dir = 70M;
memory_limit = 512M;
max_input_vars = 5000;
suhosin.post.max_vars = 3000
suhosin.request.max_vars = 3000

Do you know any solutions?
Thanks for support!
