    It is fresh localhost/PC install, only with “Error log monitor” plugin installed.

    Where is problem?
    Thanks you

    It’s likely that one plugin. There is no “field list” table in a default WP installation. If you deactivate the plugin, the error should not appear.

    Do you really need such a plugin in a localhost installation? You could just define WP_DEBUG as true in wp-config.php. If you want to use the plugin anyway, I suggest taking up the issue with the plugin developer.

    Thanks you.
    I have set define( 'WP_DEBUG', true ); but this error was not shown anywhere ( on front end/back end ), only “Error log monitor” informed me about that.
    I was working on another installation earlier that day and because my PC suddenly crashed during saving WP settings, I’ve got a lots of database errors, but again it was not shown anywhere, only “Error log monitor” informed me about that… so question really is: Do I really need such a plugin in a localhost installation?
    Is it true that define( 'WP_DEBUG_DISPLAY', true ); is default, or missed I something how to output database errors?
    Thanks you

    WP_DEBUG only outputs PHP errors. For serious DB errors a non-specific message is output and you need to check the error log for specifics. For most people the SQL error log is only filled with inconsequential notes. The debug display constant is true by default but it only has an effect when WP_DEBUG is also true.

    If your DB became corrupted due to a crash, after it is restored from backup or properly patched up, you can likely still use the monitor plugin without error if you want.
