This one took me a few days to work out, so I thought I would share it with you. I had created a copy stylesheet in the custom directory, just as the template system demands..

/includes/templates/custom/css/stylesheet.css


I wanted to do some serious work on it, so I took a backup copy before changing it, I just copied the file to:

/includes/templates/custom/css/stylesheet1.css

Thereafter, changes I made in stylesheet.css worked erratically or not at all. Why ?

The template system pulls in ALL .css files from the /custom/css/ directory, including stylesheet1.css, so any changes I made in the original stylesheet.css were being overridden by the inclusion of definitions from stylesheet1.css

If you are going to take a copy, put it somewhere else !

Just thought I might save somebody the same pain as me....
