    I wonder if the group at SLACK, who promote this plugin, know it’s not supported anymore… My site gives a 500 server error when Slack plugin is activated but the backend still works. It only happened after it passed it’s first (non-test) event to SLACK. Just tested with another of our sites, same issue. Error log shows:

    PHP Fatal error: Call to a member function is_main_query() on a non-object in …/wp-includes/query.php on line 764

    Anything…?
