We are not sure if this is related to Cache Cleaner. Want to get your input if this has been reported.

We've recently enabled auto cache cleaner (on article save).

This week a client's site crashed with error on screen (after Article was saved > then auto cache clear)

Somehow related to administrator/cache/autoload_psr4.php

Will try, thanks.

Hi Peter, we have excluded "/administrator/cache/autoload_psr4.php" 2 weeks ago from clearing cache.
The issue happened again the other day, after making content updates and clearing cache the site crashed again. We had to manually remove "/administrator/cache/autoload_psr4.php" and allow Joomla to create a new version for the site to come up.

Do you have any additional insights on this?

We have the before/after file, noticed these differences: app.screencast.com/nyXrxXIPaJuhn

Thanks Peter

Hi Peter
We still facing the issue of site went down withh autoload file.
After couple of re try we noticed it happen when the site cache is cleared.
Intersting is the file timestamp change and regenrated if the cache is clear via regular labs cache clear. Did multiple test and autoload php file got refeshed each time if i do a cache clear via Cache cleaner button.

If i do clear cache via Normal Joomla > settings > clear cache the file does not get any change.

Is there any way to ignore this behaviour or any fix would be helpfull.

Thank you

We added all these variations but noticed the timestamp on the file still changes.
