            How about if the snippet is called uncached, [[!snippet]]?
            Same story.

            It was 2.3.0, but no any result after update to the latest version.

              Is this a custom snippet? What does the final return directive of the snippet look like?

                When a snippet doesn't have a return value, PHP returns true (1) to indicate that it executed successfully. MODX replaces all snippet tags with the return value of the snippet. That's why you're seeing a 1.


                Putting this at the end of the snippet will prevent that, but don't do it for snippets that already return a meaningful value:

                return '';


                If these are your own snippets, it sounds like you are producing the output with echo or print. You should do this instead:

                $output = '';

$output = 'whatever you want to output';
$output .= 'Something more to add to the output';
// etc.

return $output;
