Here there is a link for customizing the 404 page www.joomlaplates.com/forum/j3-snowflake/...e-the-404-error-page
But this link does not work anymore. Can't find anywhere how to customize and create your own 404 page. any documentation for this?

Thanks for your answer, but I know where the error page is. This is just a php file. Does this mean there is no way to create an error page in joomla with this template, with the use of module positions? I have to create a whole individual page?

Hello,
if you want your own error page you have to create a php file.
Maybe you can take the file > layouts/theme.php and copy all content into the error.php
