Cache is empty sporadically

Ah. I see that you use WP Engine, which gives me an idea.

There is a setting to override a feature of WP Engine hosting, that truncates long SQL queries (which ours are). Edit the site wp-config.php file and add this at the top, after line 1 (on a new line 2):

define('WPE_GOVERNOR', false);

(also see here for another related support note about this – https://support.searchandfilter.com/forums/topic/killed-query-errors-in-log/#post-64826)

I would just say though, that rather than adding this in blindly, to research and make sure this setting doesn’t adversely affect anything in your site.

Thanks Trevor, I’ll surely look into this. Thanks for the tip!

Hi Trevor, unfortunately, like clockwork, empty again this morning. I did add in the “define(‘WPE_GOVERNOR’, false);” to my wp-config and confirmed nothing else was adversely effected on the site, but the issue persists. Running out of ideas.

Yes actually, there is a cron running which makes sure the other form is filled. Looks like it’s clearing out the search and filter cache.

 if(is_plugin_active("search-filter-pro/search-filter-pro.php")){
        $wpdb->query("DELETE FROM <code>lgn_search_filter_cache</code>");
        $wpdb->query("DELETE FROM <code>lgn_search_filter_term_results</code>");
 }

Is this deleting the entire cache?

If so is there a way to delete the cache of a specific form instead?
