Configuration cache is always showing invalidate in the admin panel, even after I clear the cache, it will invalidate again shortly. I'm not exactly sure which error log files to look for this problem.
Reasons for Magento page cache invalidated error Based on our experience dealing with Magento problems, we’ve seen 2 cases where Magento invalidates Page cache and users see this warning.
- Magento website owners often make changes or updates to products, categories, catalog price rules, static blocks, 3rd party extensions, etc.
- Website owners use cron jobs in their Magento application to update catalog price rules, currency rates, etc.
So, when you make changes to your website, Magento will trigger events.
There are listeners for these events and they identify that the data in the database no longer matches the data in the cache.
As a result, this invalidates the cache and displays the warning "One or more of the Cache Types are invalidated".
