Problem: You are trying to translate AltTexts for images included through the WP-Carousel plugin on your site, but when images are included through a carousel, there is no option to translate the AltTexts - they are always shown in English. Solution: We recommend modifying the WP-Carousel plugin's code to include WPML's filters for translating attachments. This change will allow you to translate the original media directly in the media library, without needing to translate the carousel or its meta-fields.
Please note that this solution might be outdated or not applicable to your specific case. If this solution does not resolve your issue, 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 you still need assistance, please open a new support ticket at WPML support forum.
