sourcerer codes are placed in standart module positions from cassiopea standart template.
dont't remeber any hack about template or 404 page...
when i try with sourcerer code in a article with volontary trunk url, the article sourcerer code doesn't appear
Only the modules sourcerer codes appear.
so... don't know what to do...
thanks
...
after a coffy, solved by a simple redirect to home page in the 404 error page
So I guess that means that the 404 page in your template has code to load in the content of modules.
But it doesn't pass that through the Joomla modules.
Maybe there is an option in the template settings to disable the lading of modules for error pages.
Otherwise you will need to ask your template developer about it.
It is not an issue caused by Sourcerer and I can not help you further with this.
