PHP Recoverable fatal error in debug.log

  • I am trying to use Query Monitor to run a stack trace on a “PHP Recoverable fatal error” I see in my WordPress debug.log file whenever I try to open a specific admin page. However, the Query Monitor console doesn’t load on the bottom of the page for that specific admin page. Any suggestions? The debug.log error message is a one liner that doesn’t provide any help in isolating the cause of the issue, so I was hoping Query Monitor could help.

    What’s the error message?

    Which version of PHP are you using? For PHP > 7 there should be a stack trace there but for PHP 5.x you’ll need to add an extension such as Xdebug in order to see a stack trace.

    As counter-intuitive as it seems, you could try defining the QM_DISABLE_ERROR_HANDLER constant in your wp-config.php file and setting it to true and see if that results in the full error showing up.

    Hi,

    I am seeing the following error message in debug.log:
    [21-Jan-2020 21:35:20 UTC] PHP Recoverable fatal error: Object of class stdClass could not be converted to string in /wp-includes/kses.php on line 1592

    I am running WordPress 5.3.2 & PHP 7.3.11

    I tried setting QM_DISABLE_ERROR_HANDLER to true, but that didn’t change the error message recorded in debug.log nor did the Query Monitor console properly show up on the page.

    Following up…I installed Query Monitor to help isolate this issue, but it seems to not load sufficiently to provide a stack trace.
