This option is available starting from Asset CleanUp v220.127.116.11 & Asset CleanUp Pro v18.104.22.168.
By default, whenever caching is cleared through Asset CleanUp, it also triggers caching clearing for other plugins. The changes made via Asset CleanUp (e.g. after updating “Settings”) would this way take effect immediately.
Some users prefer to avoid clearing Auotoptimize caching for various reasons (e.g. the resources used to clear all the plugins’ caching are high, especially on websites with lots of articles). If you want to skip clearing Auotoptimize caching (e.g. prefer to have that caching cleared manually), you can do that by adding the following constant (just one line of code) to wp-config.php (note that it should be added BEFORE the line where “wp-settings.php” is required):
define('WPACU_DO_NOT_ALSO_CLEAR_AUTOPTIMIZE_CACHE', true); /** Sets up WordPress vars and included files. */ require_once(ABSPATH . 'wp-settings.php');
In case you change your mind later on and want to have the Autoptimize caching cleared, just set the constant to false or remove/comment that line.
