I'm working on a website that has been met with the WordPress "white screen of death" error, 'The site is experiencing technical difficulties.'

I believe this occurred when updating all plugins, I have tried disabling all plugins of the website (by renaming the /wp-content/plugins to /wp-content/plugins.hold), but that did not work. I did the same with disabling the used theme but got the same result.

So after enabling debugging and looking through the debug.log, I have found this error:

PHP Fatal error: Uncaught Error: Call to undefined function register_block_type_from_metadata() in /home/uni19047/public_html/udu.com.au/wp-includes/blocks/archives.php:119

I am not sure what is causing this and I would really appreciate any help in this.

Here's the full log.

What comes to my mind is that You should check Your wp-settings.php file, as it should include wp-includes/blocks.php file where "register_block_type_from_metadata" function is defined

check that file for this line of code:

require ABSPATH . WPINC . '/blocks.php';

if its not there, then Your wordpress installation could have been either hacked or interupted while updating

As We find Out, register_block_type_from_metadata function definition was missing in blocks.php file, due to wordpress update interuption. Replacing that file with the original version fixes the problem

  • Thanks a lot! But yes there is that code in the wp-settings.php file. It appears as require( ABSPATH . WPINC . '/blocks.php' );

  • What about "register_block_type_from_metadata" function in wp-includes/blocks.php file?

  • Yes, there is no function for that in wp-includes/blocks.php. I guess that is the issue? This is the closest thing; function register_block_type( $name, $args = array() ) { return WP_Block_Type_Registry::get_instance()->register( $name, $args ); }

  • there should be function named exactly "register_block_type_from_metadata"
