Problem: After updating the WPML Multilingual CMS plugin, the client experienced a fatal error on the homepage, caused by the rawurlencode() function. The error indicated a type mismatch, expecting a string but receiving an array. This issue was resolved by rolling back the plugin version, but reappeared when certain plugins were reactivated. Solution: We recommended deactivating all third-party plugins and then reactivating them one by one to identify the problematic plugin. It turned out that the 'iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more' plugin was causing the issue when activated. We suggested checking the plugin's compatibility and configuration with WPML by visiting the Useful resources.
