Error after last update

Same here.
can’t access any wordpress administration section. the page loads as usual, no problems. but when i login to the administration panel only the error is displayed.

I re-installed the previous version for the time being.

In notification\src\Admin\CheckRestApi.php

You need to replace

		if ( array_key_exists( 'data', $message ) ) {
			$is_available = 'RestApi' === $message['data'];
		}

with

		if ( is_array( $message ) && array_key_exists( 'data', $message ) ) {
			$is_available = 'RestApi' === $message['data'];
		}

$message is not always an array but can be null.

Hey, sorry for the issue, and thanks for the fast reaction! The patch is on the way and will be live in 15 minutes

Hi, keep getting REST errors even after updating.

@metalinedev are you sure it’s coming from our plugin? I cannot see any mention of the notification in your log. If you disable our plugin does the error go away?

Yes, by deactivating the plugin the error disappears. I use Notification on several sites, now I have to deactivate it because it prevents me from editing posts.

We are seeing this same problem on many of our sites.

If we upgrade from PHP 7.4 to PHP 8.0 then we can’t edit posts and pages for any post type without triggering a fatal error.

If we deactivate this plugin, it doesn’t happen.

If we go back to PHP 7.4, it doesn’t happen.

Similar error logs as above.

We submitted a video to support on your website of what we’re seeing.

Could you help us address this ASAP? Our host is moving all sites to 8.0 in a few weeks.

Thank you!

We try to chase down the issue and replicate it in our environment. Will keep you all posted

Thanks, for the moment I am forced to deactivate the plugin on all sites.

@metalinedev @theinnographer can you send us the debug information from your website? Simply go to Tools -> Site Health and then in the “Info” tab click the “Copy site info to clipboard” button

To make sure your information remains safe, please send that over to [email protected]

Unfortunately, we weren’t able to replicate that issue in any way. A fresh WP install and PHP 8.0 or 8.1 work just fine.

Hi @kubitomakita I found out with the Kinsta team that the problem is that opcache needs to be turned on with opcache save.comments this fixed the issue for me.

Opcache save comments is an option for opcache configuration. I think it is something he should know, so he can include it in the plugin requirements.

Thanks @metalinedev for additional context! Turned out we missed the compatibility files in the last version. I just released the fix in version 8.0.14
