Good morning, i'm from italy, sorry for my little english.
My problem is:
I have a site with many linked php pages and in Nusphere it's manage as a project in a workspace, but i want debug a page that it's called by a submit button, or called from another page with link, now when i start with debug in NusphereDE the debug begin with the index.php and finish so i can't debug other pages.
Can someone help me?
Thank you
