The WPML Multilingual CMS plugin is clashing with the elementor plugin.

This thread is resolved. Here is a description of the problem and solution.

Problem:
When trying to 'Add new page' in Elementor with only the WPML Multilingual CMS plugin active, the page does not load and displays a grey spinning page. A JavaScript error appears in the console indicating an 'Uncaught TypeError: Cannot convert undefined or null to object'.
Solution:
We recommend adding the following code to your theme's functions.php file to address this issue:

//compsupp_7780 workaround
add_action( 'elementor/document/after_save', 'compsupp_7780_after_document_save' );
function compsupp_7780_after_document_save( $document ) {
    $wpml_page_id = $document->get_post()->ID;
    wp_update_post(array('ID' => $wpml_page_id));=
    return $document;
}

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Additionally, you can open a new support ticket for further assistance at WPML support forum.

Shekhar Bhandari Supporter Languages: English (English ) Timezone: Asia/Kathmandu (GMT+05:45)	Hello there, I enabled the WPML Plugin and I can edit this page hidden link without any issues, can you check if the problem still exists. Look forward to your reply. Thanks

jamesO-17	Hey, the issue occurs when you click this from that page hidden link. Did you try that?

Shekhar Bhandari Supporter Languages: English (English ) Timezone: Asia/Kathmandu (GMT+05:45)	Hello, I replicated your site on my localhost and couldn’t reproduce the issue—it opens without any problems on my end. The key difference is that I didn’t use the mu-plugins from WP Engine. I suspect the issue might be related to caching. Could you please disable all caching, clear the existing cache, and check if the problem persists? Also, do you have used any settings for role management in wpengine? Looking forward to your response. Thank you

jamesO-17	I've cleared all cache and it still doesn't work, the only thing that works for me is if I disable the WPML CMS plugin on staging and my local.

jamesO-17	Hi, can you elaborate on this please? Also, do you have used any settings for role management in wpengine? And how can I upload CSV file for logs?

Shekhar Bhandari Supporter Languages: English (English ) Timezone: Asia/Kathmandu (GMT+05:45)	Hello there, I haven't used any settings as such, but since on my localhost, if I disable mu-plugins it works so I wanted to make sure there is not an conflict with some server settings. You can upload the csv file on google drive and share the links with me. Look forward to your reply. Thanks
