    I just updated to version 2.8.0 (twice), and I am getting 1) a fatal error once after the update, and 2) Notices on every admin page load. Here are examples:

    [24-Oct-2015 04:50:34 UTC] PHP Fatal error:  Class QM_Output_Html cannot extend from interface QM_Output in C:\Users\dlingren\Documents\My Data\Data Files\Web Design\VirtualHosts\mladev\wp-content\plugins\query-monitor\output\Html.php on line 211

  • Hey – we’re seeing a fatal error message also – but only on the staging version of a site on WPEngine:

    Fatal error: Access level to QM_Dispatcher_AJAX::before_output() must be public (as in class QM_Dispatcher) in /nas/wp/www/staging/CLIENT/wp-content/plugins/query-monitor/dispatchers/AJAX.php on line 105

    As the error log identifies, switching the QM_Dispatcher_AJAX->before_output() to public resolves the issue – but the method in the abstract class is also set to protected, so not sure this is the correct route.

    Hi folks.

    @dglingren: The fatal error when you update the plugin is unavoidable because I changed a bunch of the structure of the plugin. It only happens once, though.

    Can you provide a list of all the active plugins on your site please? The PHP notices regarding an undefined line and file are caused by plugins which laod their translation files in a non-standard way. It’ll be fixed in the next release but I’d like to make sure I’ve covered all the situations.

    @qstudio: The before_output() method should be protected, so if it’s not protected in the QM_Dispatcher class then it sounds like the plugin update didn’t complete correctly. Can you try deleting and re-installing the plugin again please?

    @qstudio Cool!

    @dglingren Thanks. Looks like ACF is the culprit again. I’ll get a fix out in the next release of QM.

    I am having this problem on another site running:

    WooCommerce

    This error appeared once in the php error logs: “PHP Fatal error: Class QM_Output_Html cannot extend from interface QM_Output…”

    By deactivating & reactivating plugin error was not repeated.

    Cheers
