    I started seeing this in the logs a week ago:

    PHP Notice: The wp_cache_flush_runtime function was <strong>erroneously</strong> called. Your object cache implementation does not support flush cache in working memory. For more information, see <a href="https://www.ads-software.com/support/article/debugging-in-wordpress/">Debugging in WordPress</a>. (This message was added in version 6.1.0.) in /home/xyz/public_html/xyz-site/wp-includes/functions.php on line 5835 (note: this was translated from Swedish)

    The only plugin using wp_cache_flush_runtime is mailchimp-for-woocommerce.

    @ben72 thanks for your patience while we researched. This error is appears to actually be coming from the Action Scheduler on cache delete. From what we can tell, this is a new notice in WP v6.1 and you may be able to contact your host support desk to review how object caching is working; they may be able to flush the cache and make the log go away.

    Let us know if you need anything else.

    @khungate Thanks for your response.
    I flushed the litespeed cache in Cpanel in LiteSpeed Web Cache Manager. But I’m still seeing it in the logs.
    I’m waiting for a response from my webhost.
    For caching I’m using LiteSpeed cache on a litespeed server and Redis Object cache.
