Problem: The client was experiencing a critical error when trying to update to the newest version of WPML, which resulted in the website crashing. The error message indicated a problem with a non-countable type being passed to the count() function in a specific file within the WPML plugin. Solution: We recommended the client to check for updates by navigating to WP > Plugins > Add New > Commercial and clicking on the "Check for Updates" button. Additionally, we asked the client to provide debug information by following the steps outlined at https://wpml.org/faq/provide-debug-information-faster-support/. Our 2nd Tier Support team identified and fixed an issue related to a problematic option stored in wp_options named 'auto-translation-job-creation-error'. After resolving this, WPML was activated without further issues.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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. If further assistance is needed, please open a new support ticket at WPML support forum.
