Hi, earlier this week the back end of my wordpress site was blazing fast. Now it's back to being slow, with the intermittent error listed above. I haven't added any new plugins, I did update wordpress, but the issue spans that update. Meaning it was fast before the update, slow before the update, and now slow again afterwards.
I'm on the most recent version of WP, and the most recent version of DIvi. Yes, I know it's a monster them, but the customer specifically requested it.
Any thoughts? Any troubleshooting I can do?
