Background: My Discourse instance was upgraded to 3.3.1 a few weeks ago. My mods and myself have noticed our forum is currently timing out when trying to load post edits like below:
Is there a good place to look at where this error might be happening in the software console? More than happy to pass back logs
Yes I suspect that when logged in looking forum.example.com/logs should surface errors.
Here’s the only error I’m able to see in our logs:

Not exactly sure if this is related, just the most recent error I’ve been able to find. I’m curious if there’s somewhere that can trigger logging when pulling up edit screens since it doesn’t log these, it just looks like a client side time out. Browser inspector is indicating it’s a 500 error, is this something I can fix server side?
