  I have a site that's been running Craft 3 and has been running smoothly for several months now.
  
  I was going to update a post today, and noticed that there were updates to Craft 3 that needed to happen (there were several craft updates, along with two plugins). I selected the Craft CMS first to update, and after hitting the update button, it did its thing for about a minute, then gave me a message that the update failed. When I tried to go back to my admin panel, I got the HTTP ERROR 500. Same when going straight to the website.
  
  I tried change my php mode from FastCGI to just CGI as suggested in another post, but that hasn't helped. I also tried setting the devMode to true in my general.php config file, but nothing has changed there.
  
  At this point, I'm dead in the water.
  
  Any suggestions?
