No-no, I don’t need to edit 404 page. Sorry if I sounded not correct.
I do need to call the WordPress 404 page from my own script.
Lets see what I have now: if my script is called with non existing parameter, e.g.:
http://someblog.com/myscript.php?param=NonExistingValue
I show that “sorry, such paramenter does not exist”
Now I don’t want to show my own error. I want to show beautiful and default WordPress 404 page from _my_own_script. I guess I need to call
/%themepath%/404.php.
How can I call /%themepath%/404.php from my own script and display it? Thanks.
