Your QuadMenu plugin has an error: * `CRITICAL Uncaught Error: Call to a member function is_edit_mode() on null in/ home/cloudwaysapps.com/mydomain/public_html/wp-content/plugins/quadmenu/includes/ 3rd/elementor.php:40` * Can you review the doc I linked above? Perhaps there was an Elementor code change since your last update: [https://code.elementor.com/methods/elementor-editor-is_edit_mode/](https://code.elementor.com/methods/elementor-editor-is_edit_mode/) * I get an email everyday since WordPress 5.2 that says QuadMenu has a critical error that must be fixed. There are no visible issues on my website, so don’t know how to diagnose other than you reviewing LINE 40 in the PHP file mentioned above. * Plugin Author [quadlayers](https://wordpress.org/support/users/quadlayers/) * (@quadlayers) * [6 years, 10 months ago](https://wordpress.org/support/topic/critical-uncaught-error-elementor-php/#post-11776143) * [@gravatard](https://wordpress.org/support/users/gravatard/) please test update 1.8.7 * Thread Starter [gravatard](https://wordpress.org/support/users/gravatard/) * (@gravatard) * [6 years, 10 months ago](https://wordpress.org/support/topic/critical-uncaught-error-elementor-php/#post-11790752) * [@quadlayers](https://wordpress.org/support/users/quadlayers/) I have installed update 1.8.7 and think the error regarding LINE 40 is fixed, so thanks for that! * Now I receive a new error regarding LINE 44. Here is the email WordPress 5.2 sends me regarding new QuadMenu 1.8.7 issue: * ``` [Subject] Your Site is Experiencing a Technical Issue Howdy! Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email. In this case, WordPress caught an error with one of your plugins, QuadMenu. First, visit your website (https://www.mydomain.com/) and check for any visible issues. Next, visit the page where the error was caught (https://www.mydomain.com/wp-login.php) and check for any visible issues.
