The client is encountering a fatal error ('Fatal error: Uncaught InvalidArgumentException: target should be an object with map method or an array') when trying to translate a page using WPML. This issue might be related to a compatibility problem with WPForms.
Solution:
We recommend performing the following steps after ensuring a full site backup:
1) Navigate to WPML>>Support page, and click on the Troubleshooting link. 2) On the Troubleshooting page, execute the following actions in the *Clean up* section, waiting for confirmation after each: - Clear the cache in WPML - Remove ghost entries from the translation tables - Fix element_type collation - Set language information - Fix WPML tables collation - Assign translation status to duplicated content - Fix terms count - Fix post type assignment - Cleanup and optimize string tables - Synchronize local job IDs with ATE jobs - Synchronize translators and translation managers with ATE
If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 the problem persists, please open a new support ticket at WPML support forum for further assistance.
