How to edit 404 page?

The 404 error page can be customized by editing 404.php file in /wp-content/themes/your-theme/ folder.

There you can edit text, button (on some themes), or images.

In order to replace the background image on error page, please follow these steps:

1. First upload your image to /wp-content/themes/your-theme/gfx folder.

2. Edit the following part of the code:

<section class="bt-error-page gutter" style="background-image: url(<?php echo esc_url_raw( get_parent_theme_file_uri( 'gfx/plug.png' ) ) ;?>)"></section>

by changing the existing name of the image to that of your image.

Please note that the code might look a bit different than the example above, depending on which theme you are using.

Additionally, making larger changes to the structure of the page (code) falls under 'customization per request', so we can't assist with that type of edits.
