Was it OK before? I can’t tell what the problem is…did anything change with the site before this happened?
No new plugins added, but I did add a few new fields in a field group to start storing military service data, etc.
It was OK 3-4 weeks ago or so…
I can’t tell what the hold up is. Adding a few new fields won’t change anything like that. It looks like the database is just extremely slow to respond, but there’s no way to analyze that without looking at the logs.
I would suggest directing this question to your web host, ask them if they are seeing any unusually slow response times from the database, because unless there was a plugin update or you changed the template, I don’t see how the plugin would be the cause of the problem if you didn’t have it before.
