Custom Taxonomy / Slug

Hi Jan,

What permalink structure do you have in Settings > Permalinks?

Hi Fernando,

the link structure is set to: /%category%/%postname%/

Best,
Jan

Hi Jan,

Any chance you can check with WP's support team first as this isn't a theme-related question?

Please refer to this guideline:
https://generatepress.com/what-support-includes/

Alternatively, you can try posting the question in a WP general forum like this one:
https://wordpress.stackexchange.com/

Thanks for your understanding :)

Hi Leo,

meanwhile I was able to dig out this valuable resource that provides a solution to the problem. I'm sharing this as others may find this useful also.

The rewrite of the slugs is now working well ;-)

What I'm struggling with is the slug of the CPT Archive page. The standard slug is hilfe-chat. When I use...

$rewrite = array(
	'slug'                  => 'hilfe-chat',

...the CPT Archive page come up, but the Category Archives don't (404).

For testing purpose I added an "s" to the slug in the PHP...

$rewrite = array(
	'slug'                  => 'hilfe-chats',

As a result the Category Archives work well but the CPT Archive throws throws an 404 error.

Any thoughts on how to resolve this conflict?

Thanks, Jan

Hi Jan,

I would also suggest posting it in WP's support forum as it's not theme related.

And if you are not familiar with code, I would recommend using a plugin eg. Custom Post Type UI to create your CPT.

Hi David,

…we are probably looking at another pine of beer at the next Octoberfest for you because my next iteration did not bring the desired solution ;-/

I did follow Yings advice and found this solution.

Their advise is to add…

'has_archive' => 'hilfe-chat',

…to the rewrite rule.

I did just that and flushed the rewrite rules, but the conflict is still there.

$rewrite = array(
	'slug'                  => 'hilfe-chats',
	'has_archive' 		=> 'hilfe-chat',

Any thoughts from the expert is much appropriate by the brand new life-time GPP subscriber ;-)

Best,
Jan
