Number of items in the Menu - menu size limit by PHP in WordPress

I have a problem with the menu: when i reach a number of items in the menu, it doesn’t show all of the items. Is a max number of items that can be added to the menu or should I do something else? The website is THANX!

You have reached maximum number of menu items for WordPress. This limit is set by default PHP configuration and you can changed that. Here is a well detailed discussion about how you can increase maximum menu items that are supported by PHP by default.

This is rather advanced approach and I would strongly recommend to check if you can make your menu shorter because it is already not user friendly and adding more items will make things even worse.

Let me know if this helps.

Thank you Master! Sorted out and working!
