CRITICAL Uncaught Error (Elementor.php)

hello

thanks for reporting this issue
what is your current version of elementor?

@quadlayers There’s been several versions of WP.org Elementor since I noticed this issue and each had the same problem. I’m currently on version 2.6.1.

hello @gravatard we’re unable to reproduce your issue

can you describe the steps to reproduce the error

there are no other users reporting this

@quadlayers

Unfortunately I can’t describe the steps I took to reproduce the issue other than updating to WordPress 5.2.

Perhaps in tests you can try Astra theme, Elementor, and QuadMenu.

The QuadMenu plugin is working on my site, but have now received 24 daily emails sent by WordPress stating “Your Site is Experiencing a Technical Issue”.

In my first post, I outline where the critical error is:
/wp-content/plugins/quadmenu/includes/3rd/elementor.php - LINE 40

WordPress 5.2 does not like this line of code in your plugin:
if (!Elementor\Plugin::$instance->editor->is_edit_mode() && !Elementor\Plugin::$instance->preview->is_preview_mode()) {

I searched for some answers and will post what I found. I hope one of these leads towards a solution:

https://github.com/WordPress/gutenberg/issues/15209
https://sourceforge.net/p/concretecms/discussion/814373/thread/b5bc70b9/

FYI, SJ Elementor Addon also had this issue but the developer never resolved it:

hello @gravatard

what is the context of this issue?

customizer, admin, frontend?

Thanks for responding.

Would you mind reading through this thread? 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/

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.

@gravatard please test update 1.8.7

@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.

Error Details
=============
An error of type E_ERROR was caused in line 44 of the file /home/cloudwaysapps.com/mydomain/public_html/wp-content/plugins/quadmenu/includes/3rd/elementor.php. Error message: Uncaught Error: Call to a member function is_preview_mode() on null in /home/cloudwaysapps.com/mydomain/public_html/wp-content/plugins/quadmenu/includes/3rd/elementor.php:44
Stack trace:
#0 /home/cloudwaysapps.com/mydomain/public_html/wp-includes/class-wp-hook.php(286): QuadMenu_Elementor->footer('')
#1 /home/cloudwaysapps.com/mydomain/public_html/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters('', Array)
#2 /home/cloudwaysapps.com/mydomain/public_html/wp-includes/plugin.php(465): WP_Hook->do_action(Array)
#3 /home/cloudwaysapps.com/mydomain/public_html/wp-includes/general-template.php(2761): do_action('wp_footer')
#4 /home/cloudwaysapps.com/mydomain/public_html/wp-content/themes/astra/footer.php(32): wp_footer()
#5 /home/cloudwaysapps.com/mydomain/public_html/wp-includes/template.php(722): require_once('/home/cl...')
#6 /home/cloudwaysapps.com/mydomain/public_html/wp-includes/template.php(671): load_template('/home/2487

So this time it’s LINE 44 of quadmenu/includes/3rd/elementor.php. Apparently the call to a member function is_preview_mode() on null caused an error of type E_ERROR.

Can you look into it please?

Here is the Elementor code reference for is_preview_mode: https://code.elementor.com/methods/elementor-preview-is_preview_mode/

@quadlayers Can you look into this please?

hello @gravatard

we’ve updated to 1.8.8

please can you check if this solves the alert issue

kind regards

hello @quadlayers

I have updated to 1.8.8 and this has resolved the critical error on LINE 44 issue.

HOWEVER, now there is another critical error, LINE 35 in your plugin:

Error Details

#4 /home/mydomain.cloudwaysapps.com/domain/public_html/wp-content/plugins/astra-addon/addons/header-sections/classes/class-astra-ext-header-sections-markup.php(271

Can look into this please? I get daily emails with critical errors from QuadMenu, and have been getting them for almost 90 days straight. =(

hello @gravatard
please test update 1.9.3

@quadlayers

Thanks, I have updated to 1.9.3, and now the critical error has been replaced with this error:

An error of type E_ERROR was caused in line 70 of the file /home/domain.cloudwaysapps.com/domain/public_html/wp-content/plugins/quadmenu/includes/frontend/walker/QuadMenuItemCart.class.php.

Can you look into this please?
