It is advisable to contact your web hosting company in case you are unable to get access to error logs, when you think there might be a problem with all the servers (such as a down database) or when you are not technical enough to figure out what the problem is. Give them the time and the URL of the 500 Server Error (https://datarecovee.com/http-error-500/), and they may look into the server logs in your behalf.
