I would like to share my problem with you.
I've been having issues because everytime I go to the page#2, wordpress changes the URL to something/page/2
modifying the classes from the menu. I need to have the current menu item or ancestor.
I've doing some research but nothing clear.
Maybe someone here has the right way to do it.
I tried with wp-paginate and is the same.
Maybe someone can suggest a Hack ;)
