I have Post Indexer installed on our staging server. We are hosted by WP Engine. I'm seeing two issues.
1) The Post Indexer will not run unless I disable alternate cron. I don't want to disable alternate cron in our production environment. Is there a way to run Post Indexer on alternate cron?
2) When Post Indexer runs, it appears to run successfully on the first pass, but the second pass I get an error. See screenshot.
Fatal error: Call to private method ProcessLocker::is_locked() from context 'postindexeradmin' in /nas/content/staging/citymomsblog2/wp-content/plugins/post-indexer/classes/class.postindexeradmin.php on line 1027
