Can’t disable display of error messages

    Hi,

    I’m having trouble with the display of error messages when the plugin is active. No matter what I do, if the plugin is active, php errors display on-screen.

    I’ve noticed this behavior:
    Set WP_DEBUG_DISPLAY to false, default is true. –> checked
    entry is in wp-config define( ‘WP_DEBUG_DISPLAY’, FALSE ); but php errors still show on-screen.

    Set WP_DEBUG_DISPLAY to false, default is true. –> unchecked
    entry deleted in wp-config for WP_DEBUG_DISPLAY is deleted (completely removed from wp-config, not just set to FALSE. Still, php errors displayed on-screen. I did some tests, and at least on my site, if WP_DEBUG_DISPLAY is missing from wp-config then php errors will be displayed.

    If I disable WP Debugging and manually control WP_DEBUG_DISPLAY in wp-config, then I can control the php error displays as expected.

    Thanks,
    -Norm

    The default for WP_DISPLAY_ERROR is true, unless it’s defined elsewhere.

    WP Debugging should define that to false in wp-config.php when the checkbox is checked.

    Site Health should show you these settings in the Info tab.

    If WP_DEBUG is also true I think WordPress sets may set WP_DISPLAY_ERROR to true if it’s not defined elsewhere.

    Unfortunately the only time I’ve seen anything close to this is when another plugin like Query Monitor sets WP_DEBUG to true and the default behavior occurs.

    Is there some other plugin that might be defining one or more of these constants?

    Thanks Andy. I’m still iteratting trying to find out what might be setting WP_DISPLAY_ERROR, but I don’t have an answer yet.

    Out of curiosity… Is there a reason why define( ‘WP_DEBUG_DISPLAY’, TRUE ) is not written to wp-config like define( ‘WP_DEBUG_DISPLAY’, false) is (instead of it being deleted from the wp-config file)?

    Rather, I would prefer that if I explicitly uncheck “Set WP_DEBUG_DISPLAY to false” that it would retain & set define( ‘WP_DEBUG_DISPLAY’, TRUE ) so it is present in the wp-config file.

    Oh, hey, I just realized you mentioned WP_DISPLAY_ERROR, while I’m referencing WP_DEBUG_DISPLAY. Are we talking the same thing? I’m not familiar with WP_DISPLAY_ERROR.

    I really did mean WP_DEBUG_DISPLAY, sorry for the confusion.

    The reason that WP_DEBUG_DISPLAY is not written to the config file when it is true is that core will set this automatically when WP_DEBUG is true.

    So technically, there will be no need to set it to true in the config file.
