I do this, and it always works.
First thing in the htaccess file I insert this code ErrorDocument 404 /404.html
there are 2 pages:
in one page you create page 404
title browser: 404 You are lost
folder: /
filename: 404redirected.html
here you make your 404 page inserting as many stacks as you want
then you create another one, this must be an Offsite Page
Browser Title: The Real 404
Folder: /
Filename: 404.html
in offsite options enter URL i.e. the real address of the 404redirected.html page, in your case https://www.seminarhaus-deinsdorf.de/404redirected.html
If I explained myself badly, tell me and I’ll make you some screenshots
Unfortunately both examples given above are no SEO conform 404 pages. Why? Because the http error code won’t be 404, but 200. With this, Google won’t be able to see that the given URL is wrong.
you are absolutely right it is a 200, however there are many advantages to having a custom 404 page for website set up like this:
helps visitors find their way: by including a series of links to the most popular pages of your site or inserting a site search and helps the visitor who is “lost” to continue browsing the site.
Also the fact that a “friendly” and fun 404 page will be able to help prevent the visitor from leaving your site permanently
You’re correct. Just stating the fact that, the way how RW is building the paths to the CSS file includes will break the display for a standard (customized) 404 page for most of the themes.
You could perhaps manually set up absolute links on that page to reference the page css/js. e.g. add the following to the <head> code section in that page’s RW’s page settings.
in this way, creating two pages, it always works because the 404 page redirects to the custom 404 page with its css and stacks.
You will never have any problems.
