HTTP 404 Error Page

Hi, I would like to customize the 404 error page, usually in the other themes there is a specific page to customize while here I cannot see it. Where can I make changes without making a mess?

Thank you for your help

Hello @svanzy,

To modify the 404 not found page go to your WordPress installation folder > wp-content > themes > illdy > template-parts > content-none.php

There you can find the 404 error page content.


Thank you!!!

I did modify the words on the page but I would also change the template: instead of appearing as a blog post/article (with the menu on the right hand side recent posts, categories and whatsoever) I would prefer to use a page (nothing on the right). Is this possibile? What do I have to change to obtain this?
Thank you

Any chance I can change the class of the page from error404 to singlepage no side bar?
Thank you

Hello @svanzy,

I’m not sure I understand the question.

You can hide the sidebar from the error404 page if that’s what you want, via some CSS code:

.error404 #sidebar{
display: none;

Let me know if this is what you were looking for.


Yes it was!! Thank you very much.
