My store uses v1.3.9h which is current as of today.
There are very extensive css changes and a few code changes. All revised files are in override directories.
I am trying to add custom php pages to the "more information" sidebox.


Here is what has worked:

Added the following line to includes/modules/sideboxes/override/more_information.php

$more_information[] = '<a href="' . zen_href_link(advanced_search) . '">' . 'advanced search' . '</a>';

OK. Worked perfectly. The link showed up and the expected page loaded. A page with a header, sideboxes and footer with an advanced search "panel" in the main area. Problem is, that 'advanced search' is not the page I want. I just used it as a test of concept.



Here is whats not working:

Opened: includes/english/advanced_search.php
Saved it as: includes/english/advanced_searchxx.php
So now There is a duplicate page with a slightly different name in the same directory.

Then added the following two lines to includes/modules/sideboxes/override/more_information.php

$more_information[] = '<a href="' . zen_href_link(advanced_searchxx) . '">' . 'advanced searchxx 1' . '</a>';

$more_information[] = '<a href="http://wwwmysite.com/index.php?main_page=advanced_searchxx">' . 'advanced searchxx' . '</a>';

The links showed up just fine. In both cases hovering over them showed what I think would be the correct address (in status bar):

h t t p : / / w w w. mysite . com/index.php?main_page=advanced_searchxx (spaces intentional)

But what loaded was the usual page but instead of the expected content there was a:
Page Not Found Custom 404 Error Page.........
By the usual page I mean the correct header, sideboxes, footer, yet the main box content was the 404.

SO:

What's happening is that the cart cannot see the new page that I created.
Its seeing the old page just fine. Maybe it's an issue of the "new" page not being "registered" somewhere, but I have no clue about that.

The site is s o f a b e d - m a t t r e s s dot com
The more information sidebox is called "Mattress Information"

If I could get this to work, then it would be easy to make additional pages which would be linked to via the "more information" sidebox.

Please help.
