Create a 404 page / prevent Theme from redirecting to index

[mw]

Hello :)
I'd like to have a custom 404 page. Unfortunately this dosen't seam to be possible since LayTheme (or wp) is redirecting wrong links to the index page.

This is my .htaccess file - I think the problem is the part after #END WordPress with the 301

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

I know I need to add something like this:

ErrorDocument 404 /not-found-page.php

And probably need to delete the rewrite Engine stuff, but I am scared.

Could someone help me?

Kind regards,
Markus

Sure, no problem @Richard , I can imagine!

hey you can create a file called "404.php" in lay themes folder "wp-content" → "themes" → "lay"

however, every time you update lay theme that file will be deleted

or you could try and find a 404 wordpress plugin

other than that, please contact your webhost about htaccess questions, its not lay theme related

Alright, Thank you @arminunruh !
