Problem:
The client is experiencing PHP warnings on their WordPress site related to the WPML plugin. The warnings are due to the

wpml_upgrade_status

option in the

wp_options

table being a string instead of an array, which affects the

array_key_exists()

and causes illegal string offset errors in

CommandsStatus.php

.
Solution:
First, we recommend updating the WPML plugin and all its add-ons to the latest version, currently 4.7.6, to ensure all recent fixes and improvements are applied. Update instructions can be found here: http://wpml.org/faq/install-wpml/.
If updating does not resolve the issue, we suggest removing the

wpml_update_statuses

entry from the

wp_options

database table after making a backup of your database.
If the problem persists, please provide us with a staging site or a Duplicator copy of your website for further investigation. Instructions for creating a duplicator copy can be found here: https://wpml.org/fr/faq/provide-supporters-copy-site/.
