Cache keeps getting deleted

Here’s an update for anyone having the same issue of Monarch plugin clearing Autoptimize / Cache Enabler cache. A reply from the Elegant Themes support:

Hello there, this is the intended behaviour. To disable it, you can go to Appearance -> Plugins > Editor -> Monarch -> /core/components/init.php and remove:

// Complimentary Performance Plugins // Autoptimize if ( is_callable( 'autoptimizeCache::clearall' ) ) { autoptimizeCache::clearall(); }

thanks for following up on this @martychc23! maybe ask them to make this an option or at least disable-able with a filter instead of having to change code?

I did ask why this is default behavior as it seems like a strange thing to do they said:

“Our developers took this decision because it was probably causing caching problems”

Looking in the code there is a whole host of other plugins it seems to clear cache for also:

		// Cache Plugins
		// Comet Cache
		if ( is_callable( 'comet_cache::clear' ) ) {
			comet_cache::clear();
		}

		// WP Rocket
		if ( function_exists( 'rocket_clean_post' ) ) {
			if ( '' !== $post_id ) {

			} else if ( function_exists( 'rocket_clean_domain' ) ) {
				rocket_clean_domain();
			}
		}

		// W3 Total Cache
		if ( has_action( 'w3tc_flush_post' ) ) {

		}

			if ( '' !== $post_id && function_exists( 'clear_post_supercache' ) ) {
				clear_post_supercache( $post_id );

		}

		// WP Fastest Cache
		if ( isset( $GLOBALS['wp_fastest_cache'] ) ) {

			}
		}

			}
		}

		// Hosting Provider Caching
		// Pantheon Advanced Page Cache
		$pantheon_clear     = 'pantheon_wp_clear_edge_keys';

Will suggest to them to make this optional!

and did they say under which circumstances monarch does all of that cache-clearing?

No, the support guy didn’t seem to know exactly why this is implemented. But it occurs whenever a post is published, a post is deleted, or when activating/deactivating plugins.

I suggested they make this optional so it’s easier for novices to make the change if desired, or use a filter as you suggested, and they said they will pass it on to developer.
