you can try to increase the max_input_vars in you php.ini (http://anothersysadmin.wordpress.com/20 ... big-forms/)
Adding the directive into php.ini or placing following lines into .htaccess will work:
Code: Select all
php_value max_input_vars 3000
php_value suhosin.get.max_vars 3000
php_value suhosin.post.max_vars 3000
php_value suhosin.request.max_vars 3000
