Hi,
I'm creating Gutenberg blocks using MB Blocks and Builder. Whenever I click on a block to edit it, I get this PHP error in the log. It only happens when MB User Meta or MB User Profile is enabled.

Hi Drake,

Something goes wrong with the function get_current_screen() and it does not return a screen object which always has the property id.

Please try to edit the file /wp-content/plugins/metabox-meta-box-aio/vendor/meta-box/mb-user-meta/src/DuplicatedFields.php and check the object $screen on line 31, the code should be

$screen = get_current_screen();
if( ! is_object( $screen ) ) {
    return $html;
}

Then clear the log and edit the block again. Let me know how it goes.

Experienced the same issue here.
The website was super slow on the Ajax Requests from MB Blocks.

I applied the correction mentioned in DuplicatedFields.php
and also in UserFields.php (line 37).
After this the website was normal again.

Will this patch be on the next update?
I want to be sure that those 2 modifications won't be overwritten next time with the plugin update.

Thanks
