I wan to create dedicated table for 500 errors same like included for 404 errors, but i cant't find data with "Request / Referrer" column. What data should i use for 500 errors?
Unfortunately it's not possible to create a custom table for 500 errors that will look like the table for 404 errors. If you wish to get information on both request and referrer in the same table, you can only choose "File name" as main data and "Referrer" as group data (or vice versa).
