Custom Header on phpBB3...includes?

[Astonephus]

In previous versions of phpBB I have edited the /includes/page_header.php and /includes/page_footer.php and have done a php include of my headers and footers for my layout.

I've seen a number of threads talking about now needing to edit overall_header.php and overall_footer.php for each Style to get this same effect. I've done this and it works for the most part, but I've noticed it doesn't seem to let me do php includes or at least they are not being honored. For instance, in overall_header.php after including the portion for my header just above </head> I also want my navigational bar included though the following does nothing.

<? include "navbar.php"; ?>
(obviously w/ the correct path and what-not)

In phpBB2 you could do php includes in this manner in the page_header.php and page_footer.php files and they were honored. What is going on here? Ideas?

By default, php includes are disabled for template files because of security concerns. See http://startrekguide.com/community/viewtopic.php?f=50&t=1325 for more.

You should though be able to use the INCLUDEPHP template tags in template if you allow it in ACP :
