I have problem with my wordpress website, however, I'm trying to change menus and when I make changes and then I click "Save", blank page is shown after few seconds. This menu contains a lot of menu items. However, when I try to edit a menu that contains less menu items, everything's okay.

What should I do?

Also I've found this error in my error log and have no idea how to fix them. I'm php developer by the way.

Edit: I have found that after 17. menu item, any change to menu gives blank

blank page means syntax errors. Use error reporting. Add error reporting to the top of your file(s) right after your opening PHP tag for example <?php error_reporting(E_ALL); ini_set('display_errors', 1); then the rest of your code, to see if it yields anything. - Funk Forty Niner
Yes, usually, but how could I edit another menu with no problem? Also I'm using &debug=1 in url. Thank you for your comment. - harisdev

It was due to php.ini variables. I increased these:

suhosin.post.max_vars 
suhosin.request.max_vars
