Resolved URGENT: Unexpect500 Internal Server error

[brownbag]

Hi all.
I'm getting a 500 Internal Server error whenever I try to access my sites (on all subdomains). It was all working fine last night but woke up to see this error.

I can access the file system, database etc and that is all fine.

I'm not out of disk space and CPU usage is good.

I've tried a restart but I'm not really sure what else to do and it is a critical system. I can't see anything obvious in the logs.

I'm trying to find the web.config file on my system in order to modify it to give more detailed error messages but I don't seem to have such a file on my filesystem. What is the equivalent?

Are there any other ideas on how to diagnose this? If someone is available and can assist directly through screenshare, I'd be happy to cover your costs.

TIA.

See post: Website suddenly started to show 500 error: AH10292: Invalid proxy UDS filename - was an issue for my servers where apache had been updated.

On waking, I have encountetered the same today, 32 sites down issuing the same error. I used plesk tool to check for errors and none were identiified. I then carried out a soft restart and am no longer able to access the server with MariaDB also unreachable.
