    Hi all,

    I am trying to fix error 500 that appears on some pages in my Wordpress site.
    - Wordpress debug log does not log this error (logs all other relevant activity, though)
    - /home/<user>/logs/<domain>.ftp.log doe snot log this error
    /var/log/apache/error_log -- does not log this error
    No local error_log files generated

    Where else can it be?
    Using PHP-FPM handler with PHP 7.3

    Thanks,
    Rudolf

    Hello Rudolf,

    From your message, I believe it could be because of a plugin or a script running on those pages alone ? Did you explore that possibility ? I understand the situation and we had a couple of similar cases, but following the options and tips mentioned in the Wordpress KB , especially the SCRIPT_DEBUG helped. - Debugging in WordPress | WordPress.org

    Hi,
    It is most likely a plugin causing this. Page is a generic one from Wordpress (custom post creation), but one of the plugins is likely to act on it. As this is a live site, I am a bit hesitant to start disabling plugins. I am trying to duplicate the site at the moment, so I will be able to do a bit of destructive testing.

    SCRIPT_DEBUG variable only really applies to debugging JS and CSS -- this one forces Wordpress to supply normal, non-compressed version of those scripts.

    Still not explaining why error does not appear in logs. I thought it should be reflected in one of the logs.

    Rudolf

    On a scenario we've saw in the past, the culprit was the Apache LogLevel setting.

    Just in case, you can double check in your WHM (Apache configuration -> Global Configuration) and look at the LogLevel setting.

    Your should make sure the LogLevel is at "warn" so that most regular errors will be logged in "/usr/local/apache/logs/error_log" file.

    If you're running PHP-FPM you'll find that there is an error log for PHP-FPM in /home/user/logs/domain_tld.php.error.log
