Set up error pages for Typo3 correctly

During a relaunch, for example when the web design of a Typo3 website has been revised, the internet agency should ensure that the existing structure is not lost.

Error pages as of TYPO3 version 9.5

As of version 9.5, the definition of error page handling has changed and, above all, been simplified.

All properties of the website, domain, etc. are defined under Page management / Pages.

There is an Error handling tab. This is where, for example, the redirection is set up.

Information on setting up error pages under version TYPO3 9.5 can be found here:

During a relaunch, for example when the web design of a Typo3 website has been revised, the internet agency should ensure that the existing structure is not lost.

If it cannot be avoided, an entry in .htaccess can be used to redirect old pages to a new URL to tell Google and co. where it is now.

For all other cases, create a normal page under Typo3 with the property "Not in menu". In this case, this page is not included in the menu structure and is a kind of island page.

This option can be found under "Access" in the page properties.

Typo3 error page

Now Typo3 (here from version 6.2) still needs to be told where this page is located or which ID it has.

There are two ways to do this:

1. entry in LocalConfiguration.php

'FE' => [

  'pageNotFound_handling' => 'REDIRECT:http://dbje.de',

 'pageNotFound_handling_statheader' =>'HTTP/1.0 404 Not Found';

],

2. via the Typo3 install tool

Under "All configuration" in the Frontend (FE) field, select the entry

[FE][pageNotFound_handling] =

search. The URL is specified there.
