An error of type E_ERROR was caused in line 84 of the file class-wpml-ls-widget.php

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

Problem:
After updating WPML plugins, you are unable to see your created widget areas in the WordPress admin alongside Avada theme's widgets. Instead, an error of type E_ERROR occurs in

class-wpml-ls-widget.php

due to corrupted serialized data in the "widget_icl_lang_sel_widget" option key.
Solution:
We recommend deleting the corrupted "widget_icl_lang_sel_widget" option key from the wp_options table in your database. This action should resolve the issue with the widget areas not displaying correctly.

If this solution does not apply to your case, or if it seems outdated, please check the related known issues and confirm that you have installed the latest versions of themes and plugins. If the problem persists, we highly encourage you to open a new support ticket.

Bruno Kos WPML Supporter since 12/2018 Languages: English (English ) German (Deutsch ) French (Français ) Timezone: Europe/Zagreb (GMT+02:00)	To troubleshoot this problem, I'll install the Duplicator plugin and generate packages for further debugging purposes. I'll ensure to exclude all media files to maintain a minimal package size. You can find more information about the process here: [link](https://wpml.org/faq/provide-supporters-copy-site/). Please confirm if this approach is acceptable to you.

manuelS-24	Sure. Duplicator is already installed in the staging site. I also created a package earlier, but feel free to create another package if you like.

Can you delete it from wp_options table?
