PHP-Error in complex situation

Hi,

we have a case in the German-language forum where someone is encountering a fatal PHP error related to your plugin in a rather complex situation. However, I can reproduce it perfectly on a test system. Here’s how:

• Install and activate the plugin (no further configuration required)
• Install and activate Elementor (the free version, no further configuration required)
• Install and activate the Astra theme (presumably optional, but it works well)
• Install and activate Sugar Calendar Lite
• Go to Events and create a simple event scheduled for the future
• Go to Settings > Permalinks and save them again (because Sugar Calendar apparently doesn’t do this automatically)
• Go to Events > Calendar and access the only calendar listed there on the frontend => you’ll see an incomplete page, as this is when the error occurs.

The error:

 PHP Fatal error:  Uncaught Error: Call to a member function is_built_with_elementor() on bool in /var/www/clients/client1/web1/web/wp-content/plugins/embed-privacy/inc/integration/class-elementor.php:134

What’s happening here:

• Sugar Calendar Lite uses a “Virtual Event ID” with the fixed value 7575000 in Loader.php.
• Embed Privacy takes this value in the is_used() function in class-elementor.php and passes it to Elementor.
• Elementor doesn’t return an object for this pseudo-ID when using Plugin::$instance->documents->get( \get_the_ID() ) => Error

Recommendation:
You should check if the passed ID is a real one and/or if Elementor returns an object before calling is_built_with_elementor().

Unfortunately, I’m not aware of any other solutions, which is why the user in the forum is a bit stuck here 🙁

Feel free to contact me if you have any questions 🙂
