REPEATED REQUIRES ISSUE
I am sorry that that is still not working.
I copied the Develop Notes into the file in Dreamweaver.
And the first thing I noticed was that each of the three had a "require" command.
I therefore and immediately felt that this was not going to work, but prepared to upload anyway.
And just as I was about to upload, Dreamweaver gave me the warning that the file on the server had been amended.
I therefore decided to go and have a look, and I saw the file you had uploaded.
This had but a SINGLE require_once command, and it worked appropriately. It even saved back to where it should when I clicked the Hide Edit button (or whatever)
Having given that a runthrough, I then uploaded the verstion you will see there now, and that contains three separate require commands, the net result being that it dispays only a single line of PHP code, with zero content from the CMS.
The solution, obviously, is that somehow each relevant page must show only a single require_once command, and as you had in the working one I played around with before overwriting it..
(PS I will retest the template functionality so there is only a single issue at a time).
