Hey People I hope that today I can give something back to the community. I have been struggling with this for ages.
When I create a new site often when using Firebug I cannot get the CSS File Locations to display when I a using JAT3. Today I figured out why.
If it is happening to you go to your admin view then to your JAT3 Template. On the Global tab make sure you have all of the following
Enable Development Mode
Yes
Enable Template Information
Yes
Optimize CSS = No
Optimize JS = No
Optimize Folder = t3-assets
must be writable
As soon as I change these all was fine. This seems to happen when I am copying a modified JAT3 Template on the original I had these settings as reccomended but when I copied the template to another site they seem to change the optimise settings to Join, Minify & Compress.
I really hope this helps someone as this had me stuffed for ages. :p
