To date i have just been using the HTML/CSS stuff. However I wanted to explore using either PHP or SSI to generate some standard items in my pages, rather then having to paste them in each page.
I have installed Apache & PHP, and got a couple of basic scripts which work when in the server document root directory.
However, I did not want to be always moving my pages to that directory, so i looked around in WeBuilder and came across the Preview mapping option. Well, this worked fine on my test PHP files, both in the WeBuilder preview and when previewing in a browser

I then tried a simple shtml file from same path [with a single include] statement [no php]. When i tried to preview this I get a 'Page cannot be found error'.
I finally tried a straight HTML file, again from same path, which has always worked, and still get this 'Page cannot be found error'

is this correct, i.e. if i use preview mappings to preview a PHP file, then it stops preview of HTML, or have i done something wrong?
thanks for your help
