XF 1.2 Server error

Hello, I have had this Server Error happen multiple times. I fix it by just installing a upgrade but that's just a temp fix. It happens again days later. I am not sure what is going on but I need to get it fixed.


If anyone has any suggestions, please tell me. I need to get this fixed.

It's a generic 500 error so difficult to debug.

You need to check the server error logs to see if there's anything there.

Also try disabling all add-ons to determine if an add-on is the cause.
Question is, do I disable a plugin then wait til it does it again? As said it does it like once every few days. Can you tell me where I can find the certain log I need to check?

I don't know where your errog log is, probably something like var/log/error_log.

Ask your host if you don't know.
I found this in the Apache2/Error.log

Any ideas?
