thank you, unfortunately since it only occurs overnight, the site will need to be down for several hours, for several days just to troubleshoot and find the specific plug-in causing the problem. I was hoping it was something new that I missed in the update. If I figure it out I will update here in case anyone else encounters a similar issue
Thank you @t-p, this will probably be a stupid question, but will disabling all plug-ins affect current posts and pages built with or using those plug-ins when they are re-activated? same question RE: template, because that would be a nightmare to go through.
