Intermittent Website Crash Fix

Every day or two the entire site goes down without warning and I’m forced to roll back from a backup. I believe it is related to a faulty plug-in but not sure.

I need you to dig into whatever layer is responsible and pinpoint the failure trigger, and eliminate it so the site stays stable 24/7. Access to word press admin site will be provided. Host site access is possible with screen sharing

Deliverables
• Root-cause for the crash
• Configuration fix applied

Acceptance
The site must run continuously for a minimum of five consecutive days without the need for manual restoration, and load times should remain at least as fast as they are now.
