I am trying to: Open the content Layout Editor

Link to a page where the issue can be seen: hidden link

I expected to see: the content layout editor

Instead, I got: the content layout editor waiting eternally to open and a message about a critical error on the bottom

The error log reports:

Een fout van het type E_ERROR werd veroorzaakt op regelnummer 1334 van het bestand /home/pkbsur/public_html/wp-content/plugins/layouts/classes/wpddl.class.php. Foutmelding: Uncaught TypeError: method_exists(): Argument #1 ($object_or_class) must be of type object|string, null given in /home/pkbsur/public_html/wp-content/plugins/layouts/classes/wpddl.class.php:1334

Hi Erik

I was able to reproduce the problem on a local test site. It occurs after updating PHP to 8.x (I'm not sure what version exactly).

I've escalated the issue to the developers, but I identified where in the code the problem arises, and as a workaround until Layouts is updated you can workaround the problem by updating the file plugins/layouts/classes/wpddl.class.php

Around line 1334 you should see the following if statement:

if ( is_object( $layout ) === false && method_exists( $layout, 'get_post_slug' ) === false ) {
	return null;
}

Please change that to look like this:

if ( !( is_object($layout) && method_exists($layout, 'get_post_slug') ) ) {
	return null;
}

The next update to Layouts should include the fix as it is very simple, though I'm not sure when that will be.

Let me know that it works.
