HTTP 500 error on OJS 3

I am getting http 500 error at https://tinyurl.com/ydczoxd3
It is OJS 3. It was working yesterday.

I have set to show errors and DB debug on config file but I see nothing.

Any ideas what might have gone wrong?

Hi @Taz,

There will definitely be something logged on your server – check the FAQ area for a post on how to find the log.
