Si i`ve just change from b2 to b2evolution and i`m having some questions

i have some pages that has more info on the site and are separate php pages, i want to display here the calendar and archive.

With b2 i just added the line php at the beggining and then i could display the php calendar using the code and the same goes to the archives one so it can display in all the pages of the site.

Can i do this on Evolution? cause i used the same method i did to b2 and i get the message, "please dont access this page"

thank you, if you want to know how i have my site you can see it here: http://www.nsyncmexico.com
