WHAT IS THE 404 ERROR PAGE?
The 404 error simply means that a web page does not exist at the current URL or the Website can’t load it due to an updated link.
This problem typically occurs when new post types are added or dynamic pages (like our frontend submission page) are enabled for the first time.
How to fix it?
If you encounter the 404 Page Not Found error (screen above), please go to the
recheck page URL and reload.
This should flush the website cookies, making the missing (404) page accessible.
