I have installed "Advanced CSS/JS Aggregation" on my Drupal 10. but after installation, I faced a problem.
In performance page, when I want to save configuration (for example I checked/Unchecked Aggregate CSS files & Aggregate JavaScript files checkboxes and want to update config.), I see this error
'stale_file_threshold' is not a supported key.
I tried to check aggregator settings. but I found no solution. I replaced alpha version with .dev version. but problem hasn't gone. Even I uninstalled and remove the module, but problem still exists and I can't save performance configuration.
what is your solution?
