Comments Plus crashed my site – part II

Hi — I’m responding to the earlier response (thanks!) to my previous support request as I could see any way to actually respond to that response. In any event, yes, it crashed the site as in, the instant the plugin loaded the site when down–poof–I called WPEngine emergency support and they pointed to a cascade of fatal errors that had been triggered the moment the plugin went live, shutting down the entire site. Is this a new plugin? Thanks again for the response. Sorry to be starting a new thread like this.
