The URL
And now I had to hide the GET variables from the URL. But the problem arose. I used ErrorDocument 404 to organize the structure in the php code. We did not immediately solve this task.
Gennady had to find out in my index.php and he separated from it in htaccess the entire structure, provided that ErrorDocument 404 we refuse. I am so happy.
He also prepared index.php, to which I’m already transferring my entire code.
In general, I thank Gennady for not giving up my task at such a difficult time!
