The sample 404 page on the template is a screen shot, not the actual page to modify... I've tried.
Back to the question...
I purchased an extension where I can create custom error pages. It is installed and I created a custom 404 page. ~but~ the JA template / T3 system overrides the extension - it ignores it.
How to I tell the JA/T3 system to stop processing the errors?
Thanks for the quick follow up.
Future Request: build a error handler into the templates - you guys are buying a bunch of other extension companies. Buy one that has helpful admin tools and embed them into your templates....
