I am testing the creation of custom pages and their main menu appearance. I have created a page called 'My Page' and the link appears in the footer as it should. When I add it to the top menu bar however the hyperlink [page.php?page=mypage] is correct (it links to the newly created page 'My Page') but instead of the menu displaying the text 'My Page' it displays MENU_MYPAGE
 
Could anyone help with this please?

[Solved] It appears that the form MENU_PAGENAME ( e.g. MENU_FAQ) is only entered for the predefined pages. Custom pages simply require the title without the 'MENU_' prefix. In the example I used above this would simply be 'my page', not MENU_MYPAGE.

I'm wanting to change "products" to "stock items" on my site, anyone know if I can simply delete MENU_PRODUCTS and substitute with "products" on the sitenav, menu title?
 
Many thanks
