We can insert a new post via wp_insert_post(). We can couple that with, is_404() to know if the current page we're on is a 404 page.
Then we need to study the request to know if it match our criteria. We can fetch the request via $request = $_SERVER['REQUEST_URI'];. We need to isolate the page, which should be the last request /1197-pomoc-pytania-problemy/, and the category /forum/, which is the prior to last one.
We can redirect the user to the post via wp_safe_redirect() and capturing the post ID upon publishing.
Tested and working.

return substr( $haystack, -$length ) === $needle;

if ( ! function_exists( 'insert_new_post_on_404_request' ) ) {
function insert_new_post_on_404_request() {
if ( is_404() ) {
$request = $_SERVER['REQUEST_URI'];

$request = $cleaner;

$postarr = array(
'post_title' => $current_title,
'post_status' => 'publish',
'post_type' => 'post',
'post_category' => array(
$cat_id,

Some things to take into account:
- Category terms (topic, forum and profile) need to exist prior to initialize the function for the first time.
- The function will only insert posts from a fail request, on a
404.php page, if 1 of those 3 category a present in the url.
- If a request is made for a child page, it will likely create a post not attach to any category. the function can't understand that it is supposed to be a child page, so I don't see any way to handle those type of request.
Additionally, translation should be handle on it's own. either through a plugin or else. You can also rewrite each category name and slug. This is based on your theme initial development; Not much we can do here.
