Changing PHP-version disabled APCu-manager function without any info

Hi,

I encountered a strange phenomenon in one of my projects today (and solved it, just read the following). I noticed that WP Cron wasn’t being processed. WP Crontrol showed me hundreds of entries. APCu Manager suddenly displayed the options for APCu as grayed out, which only happens when PHP-APCU is missing.

Explanation: I had switched from PHP 8.0 to 8.3 a few weeks ago and hadn’t installed PHP-APCU for 8.3. So the project had an active APCu Manager plugin that suddenly lost its technical basis.

As soon as I installed PHP APCu for PHP 8.3, WP Cron was processed and the fields are not grayed out anymore. Apart from restarting the PHP service, I didn’t do anything else at that moment.

My wish: APCu should indicate when something unexpected has changed in essential areas – for example, when PHP-APCu is suddenly no longer available.

And yes, I know: warning messages in the backend are annoying. But maybe as an error message in Site Health? That’s where I looked first to check the crons… 🙂 Would be nice for one of the next updates 🙂
