Duh.....i probably didn't give enough info last night. It was late!!
the site is
www.lowcarbjourney.com and I'm just getting it started. There's not much there yet so I was going to do the php includes for the header, menu bar, left bar and right bar.
I thought I followed the instructions by the letter, but obviously not......
The header is saved on page "header.php"
I'm trying it on a page named "myths.php"
