Description
This plugin clears OPcache after updating WordPress core, themes, and files.
Unlike other plugins, it is also compatible with WordPress updates made by Linux cron.
Features
- Automatic OPcache reset after plugin/theme/core updates
- Clears both memory-based and file-based OPcache
- Works with cron-based WordPress updates (CLI context)
- WP-CLI commands for manual OPcache management
- Zero external dependencies (optional cachetool support)
Configuration
The plugin works automatically for web-based updates. For CLI-based updates (cron, WP-CLI), configure your PHP-FPM socket:
Option 1: Create .cachetool.yml in your WordPress root:
adapter: fastcgi
fastcgi: /run/php-fpm/www.sock
Option 2: Use cachetool binary (if installed in PATH)
WP-CLI Commands
Reset OPcache from the command line:
wp opcache reset
Show OPcache status and statistics:
wp opcache status
Output status as JSON:
wp opcache status --format=json

This almost what I have been looking for. The OPCache is also reset when installing new plugins, but not when deinstalling.
